The day of Pentecost is typically associated with stupendous signs and miracles. Acts 2:1-11 records that when the Holy Spirit was given, the display of ability and power astounded everyone present. There was a sound like a mighty rushing wind (verse 2). It appeared that fire rested on the apostles (verse 3), and when they spoke, every person present could hear what was being said in his own language, even his own dialect (verses 4-11).
Because of the brief description given in Acts 2, various religious denominations have sprung up which practice speaking in gibberish—which the disciples definitely were not doing—and being "slain in the Spirit," which is clearly not a biblical concept. These sincere but misled people focus on miracles and manifestations as "proof" that they have received the Holy Spirit. Every week they gather to "pray down" the Spirit—or at least a spirit—for their own use and gratification. The focus of their meetings is on the experience rather than on instruction, admonition, rebuke, or encouragement (see II Timothy 3:16).
Before this event in Acts, Jesus Himself explained to His disciples the importance of their receiving the Holy Spirit, as well as what signs would be shown as a result:
And being assembled together with them, He commanded them not to depart from Jerusalem, but to wait for the Promise of the Father, "which," He said, "you have heard from Me; for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now." Therefore, when they had come together, they asked Him, saying, "Lord, will You at this time restore the kingdom to Israel?" And He said to them, "It is not for you to know times or seasons which the Father has put in His own authority. But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth." Now when He had spoken these things, while they watched, He was taken up, and a cloud received Him out of their sight. (Acts 1:4-9, emphasis added)
The very last thing the resurrected Christ said before He ascended to the Father was, to paraphrase, "You will receive power when you receive the Holy Spirit, and this will enable you to be witnesses of Me." Through the giving of the Holy Spirit, Christ's disciples would have the necessary means to be lights to the world and to demonstrate a way to live that glorified God.
God chose ancient Israel out of all the nations of the earth and determined that they would be a holy nation. He ordained that they would be a people set apart from the rest of the world. The Old Covenant was intended not only to be a schoolmaster to teach Israel how to live in such a way that they would recognize the Messiah when He came (Galatians 3:24), but it was also intended to set Israel apart—to make them holy. In so doing, He intended the entire nation to be a witness of Him. Deuteronomy 4:5-10 demonstrates this:
Surely I [Moses] have taught you statutes and judgments, just as the Lord my God commanded me, that you should act according to them in the land which you go to possess. Therefore be careful to observe them; for this is your wisdom and your understanding in the sight of the peoples who will hear all these statutes, and say, "Surely this great nation is a wise and understanding people." For what great nation is there that has God so near to it, as the Lord our God is to us, for whatever reason we may call upon Him? And what great nation is there that has such statutes and righteous judgments as are in all this law which I set before you this day? Only take heed to yourself, and diligently keep yourself, lest you forget the things your eyes have seen, and lest they depart from your heart all the days of your life. And teach them to your children and your grandchildren, especially concerning the day you stood before the Lord your God in Horeb, when the Lord said to me, "Gather the people to Me, and I will let them hear My words, that they may learn to fear Me all the days they live on the earth, and that they may teach their children."
God proposed the Old Covenant to Israel on this same day—the day of Pentecost. Israel accepted the terms of the agreement and thereby signed up to be a light to the rest of the world. God had given them the most superior set of laws that mankind had ever encountered, which would leave the rest of the world in awe due to the beneficial effects that would come from it.
We know from the New Testament that the only problem with this covenant was the heart of the people entering into it (Hebrews 3:10-12; 8:7-8). The God-given terms of the agreement were absolutely perfect for what He wanted to accomplish. One of His main purposes was for Israel to be an example, a witness, to the rest of the world of the right way to live. Incidentally, the Tabernacle that Israel carried with them in the wilderness was even called "the Tabernacle of witness" (Numbers 17:7; Acts 7:44).
If Israel had been faithful to the covenant, they would have received blessings beyond belief. In the blessings portion of Deuteronomy 28, God was prepared to set Israel high above all the nations of the earth. Their cities and farms would be prosperous; their children would be healthy and strong; their herds and flocks would be numerous; they would have an abundance of food; and they would have protection from their enemies. They would have rain in due season, and everything they put their hands to would be blessed. They would have enough that they could lend to other nations and not borrow. God intended them to be a holy people whose behavior and prosperity would make it obvious to the rest of the world that God had set them apart. The effect would be so dramatic that Israel would be feared!
However, as we know, Israel failed. The accounts of the Old Testament prophets show the great lengths to which God went for Israel in cleaning her up and taking her under His wing. Yet, once she caught a glimpse of her God-given beauty and wealth, all she did was play the harlot with the surrounding nations, rather than being a witness to them (see Ezekiel 16).
Today, the United States is the richest nation on earth, which seems to coincide with God's promise of blessing until we realize that America is also the greatest debtor nation. Parts of the nation suffer drought, and other parts are practically floating away. Much of our food is either imported or grown from genetically mutated seed. Our cities are filthy, crowded, and corrupt, and our family farms are dying through environmental regulation and corporate buyouts. We live in abundance yet cannot afford our lifestyles, plunging further into personal debt. The nation's churches are pathetically weak, barely standing to fight the onslaught of secular culture—and, in fact, accepting much of it in a misguided spirit of tolerance. In short, America is the farthest thing from being a kingdom of priests or a holy nation. Our entertainment industry shows, like nothing else, what sort of "witness" we are making to the world.
Israel failed because her heart was not right. Biblically, the word "heart" is synonymous with "mind" and "spirit." We know that God desires that all Israel be saved (Romans 11:26; II Peter 3:9) and that in the future He will replace Israel's heart of stone by pouring out His Spirit (Ezekiel 36:26-27). However, for a few—known as the remnant, the church, the Body of Christ, spiritual Israel, the Israel of God, or the firstfruits—God decided to do this ahead of time.
He gave His Spirit on the Feast of the Firstfruits, the day of Pentecost, AD 31, so that a remnant of Israel would have a heart of flesh and not of stone. God gave His Spirit so that spiritual Israel could obey God both in the letter and in the intent of His law. In addition, as we saw in Acts 1, just as He gave Israel His law so she would be a witness, God gave the church His Spirit so that Christ's disciples would be witnesses. By receiving a portion of the Spirit that proceeds from the divine Lawgiver, the firstfruits are able to understand the intent behind God's laws. More than this, by yielding to the promptings and motivations of God's Spirit, they can begin to take on His character and actively do good rather than merely avoid sin.
God's Image in Us
If we are regenerated children of God and led by His Spirit, we will exhibit His character and spiritual image:
For as many as are led by the Spirit of God, these are sons of God. For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by which we cry out, "Abba, Father." The Spirit itself bears witness with our spirit that we are children of God, and if children, then heirs—heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be glorified together. (Romans 8:14-17)
Before God summoned us, began to reveal His truth to us, forgave us, justified us, and imparted His Spirit to us, our spiritual father was Satan! We were no better than the Pharisees, whom Christ told that they were of their father, the Devil, because they were doing Satan's works (John 8:39-47). Children display the characteristics of their parents, so Christ judged the Pharisees to be the children of Satan because they were exhibiting the Devil's characteristics.
Before God intervened in our lives, we, too, were the children of Satan (Ephesians 2:1-3), because we were exhibiting his spiritual characteristics. However, God began to redeem us and called us into a relationship with Him, which, as Romans 8:15 says, was symbolically an adoption. God was not our original father, but He took on that role after He extracted us from the grasp of Satan, sin, and this world.
Verse 16 reiterates that the Holy Spirit is intended to provide a witness of who we are and who God is. If we allow the Spirit to lead us, we are sons of God. It follows that, if we are sons of God, then we will be exhibiting the same characteristics as our Father! When we exhibit God's characteristics, we are a witness to the world of His character and the way He lives.
Under the New Covenant, with access to the Holy Spirit, the quality of our witness must be much higher than what God expected of physical Israel. To whom much is given, much also is required (Luke 12:48)! If our neighbors, co-workers, or family members look at us, and all they see are people who go to church on different days, do not eat certain foods, give multiple tithes on their income, and do not believe in the Trinity, are they seeing anything different than Old Covenant Israel, who did not have the Holy Spirit? Certainly, God's law will set us apart from the world because the world is against God, but merely keeping the letter of the law will not provide the complete witness that God is looking for.
This is not to denigrate the royal law of liberty to any degree. Acts 5:32 says God gives His Spirit only to those who obey Him. However, one can be nominally obedient, keeping God's law in the letter, without making a truly effective witness for God.
Flesh or Spirit
Paul lists various "works of the flesh" in Galatians 5:19-21:
Now the works of the flesh are evident, which are: adultery, fornication, uncleanness, licentiousness, idolatry, sorcery, hatred, contentions, jealousies, outbursts of wrath, selfish ambitions, dissensions, heresies, envy, murders, drunkenness, revelries, and the like; of which I tell you beforehand, just as I also told you in time past, that those who practice such things will not inherit the kingdom of God.
Consider this passage in light of the laws and beliefs that we frequently point to as setting us apart from the world. A person can keep the Sabbath, at least in the letter, and still display drunkenness, hatred, contentions, outbursts of wrath, and dissensions. One can reject the Trinity doctrine, the doctrine of eternal security, and the immortality of the soul yet promote and practice heresies, since a heresy is simply any deviation from truth. An individual can tithe yet exhibit selfish ambitions, envy, and jealousy. Someone can observe the laws of clean and unclean meats and still be unclean in his heart and in the decency of his life. A man can be physically pure in his relationships while living vicariously through revelries, which Adam Clark's commentary defines as wild parties and obscene music.
The warning at the end of verse 21 is explicit: Those who practice such evils or make them a part of their lives will not be in God's Kingdom because they simply would not fit in. Their lifestyle is contrary to the quality of the life God lives and expects His children to live.
To put this another way, what kind of witness does a person make who keeps the Ten Commandments (including the Sabbath and holy days), eats only clean meats, tithes faithfully, and rejects false doctrines, yet has a temper, curses, tells dirty jokes, has a perpetual chip on his shoulder, always has a complaint against another, always looks out for "number one," drinks too much, and revels in perverse entertainment? Such a witness of nominal lawkeeping is useless to God, just as ancient Israel's witness to the nations gave the enemies of God an occasion to blaspheme (Ezekiel 36:20-23).
When Jesus Christ introduces Himself in the letter to the Laodicean church, He highlights the fact that He is "the Faithful and True Witness." He points to this title to show where the Laodiceans fall short. They are so enamored of the world and so much a part of it that it is difficult for an observer to tell them apart from the rest of Babylon! Their lives do not glorify God because they do not demonstrate a separation from the world. They do not demonstrate holiness or sanctification.
In contrast, the result of the Holy Spirit being active in a person's life will be love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness (meekness), and self-control (Galatians 5:22-23). These attitudes are not manifested all at once, which is why Paul calls them "fruit." Fruit takes time to develop and mature. Nevertheless, one whose life God dominates, who is led by His Spirit, will be exhibiting these things in addition to obeying God's law. He will be not merely obeying but also imitating God. He will be exhibiting these characteristics because he is a regenerated son of God who expresses the traits of his Father.
God has given us His Holy Spirit so we can fulfill His purpose. A primary responsibility that God has given to those He has set apart over the years—whether physical or spiritual Israel—is to be a witness to the rest of the world of God's way of life. Physical Israel failed in this, and the Laodicean Christian is currently failing in this.
Yet, if we have received the Holy Spirit and maintain a close relationship with its Giver, we have the means to be the true and faithful witnesses that God desires and commands His people to be. We will obey the laws that God rehearsed to Israel on Pentecost, be led by the Holy Spirit that God endued His people with on another Pentecost, and ultimately be unified with the rest of the firstfruits of God's spiritual harvest.
