Peter said to them, “Repent, and each of you be baptized in the name of Jesus Christ for the forgiveness of your sins; and you will receive the gift of the Holy Spirit.” [Acts 2:38] 
(1) Real repentance is a type of sacrifice. It is also an apology to God. It is the means for gaining the remission of one’s sins. The blood of Jesus is applied at repentance.
It is doing a 180 degree turn-around and walking away from sin and rebellion, and toward the Lord Jesus. Through the expressing of genuine sorrow for one’s sins and especially for one’s sinning against God and one’s distance from God through one’s own willful actions, it allows the Lord to completely cleanse the heart. It allows the Lord Jesus to circumcise the heart and wash away all sin from the heart with His redeeming blood. This is the beginning of the new birth. It is wholly transformational and a complete change in soul status. Repentance is death to the old.
(2) New Covenant water immersion is indicative of an outer form of giving one’s self completely to the Lord Jesus and puts Him in charge of the heart. It furthers the remission of sins in the sense that it acknowledges the work achieved by the Lord on the cross, without which the forgiveness of sins would be impossible. The apostle Peter put it this way: …Baptism doth also now save us (not the putting away of the filth of the flesh, but the answer of a good conscience toward God,)… [1Peter 3:21 KJV]
In the original community of the Lord Jesus this was demonstrated outwardly in public for all to see through water immersion in His Name—the Name of Jesus—the Name above every name. Water baptism is both a burial of the old and then an outward demonstration of resurrection and new life rising and coming forth. By invoking the Lord’s Name, the candidate is demonstrating one’s allegiance to the Lord Jesus and no other. A person states one’s desire to become a disciple of the Lord Jesus and follow Him just as the original disciples did, and become a member of His community the same way they did. If one refuses this immersion and the invoking of the Name of Jesus, how can his or her heart be right toward Him?
(3) Once the candidate for inclusion in the Lord’s community has properly repented and has undergone full water immersion to illustrate an outward representation of an inward spiritual change and identify the Lord Jesus as one’s Master and Teacher—once the heart is cleansed and redeemed by His blood and is circumcised—the Lord is enabled to fill the cleansed heart with His Holy Spirit.
This gift of the Holy Spirit was promised by Peter at Pentecost and is available to all who obey the Lord accordingly. He said it was for every succeeding generation until the Lord’s eventual return for His community. The infilling of the Holy Spirit enables miraculous works and signs. The New Covenant writings are clear that without the evidential miraculous works and signs, there is no actual infilling of God’s Spirit.
(4) By cleansing and circumcising the heart through the candidate’s surrender to His authority and power, the Lord Jesus tames the person’s tongue and one’s speech becomes cleansed (see James 3:8).
This means that all speech flowing from the cleansed heart is as seed from a holy spiritual place rather than the prior sinful place. It is the difference demonstrated by Abel and Cain, in that since Abel was righteous he always made the proper sacrifice. All that came forth from him was spiritually good since he had a good heart toward God.
And Abel was a keeper of flocks, but Cain was a tiller of the ground. So it came about in the course of time that Cain brought an offering to the LORD of the fruit of the ground. Abel, on his part also brought of the firstlings of his flock and of their fat portions. And the LORD had regard for Abel and for his offering; but for Cain and for his offering He had no regard. So Cain became very angry and his countenance fell.
Then the LORD said to Cain, “Why are you angry? And why has your countenance fallen? If you do well, will not your countenance be lifted up? And if you do not do well, sin is crouching at the door; and its desire is for you, but you must master it.” [Genesis 4:2-7]
Cain could do nothing right spiritually and everything he tried was wrong because his heart was wrong toward God. He had no power with God. God had no regard for his offering. Cain was essentially spiritually worthless. He could never bring forth a proper sacrifice until his heart was right and he never made that choice. Because of this, he substituted dead religion and a mere form of godliness due to his refusal to obey God. This is the highest form of rebellion. Abel is a type of the real Christian. Cain is a type of the unreal Christian.
(5) The outward sign of receiving the Holy Spirit into a cleansed, circumcised heart is a yielded tongue—the last member of the body to surrender to the Lord Jesus and the first to demonstrate His indwelling presence.
As a result, a person’s speech becomes a vehicle for God’s glory and ministry. One’s speech is a person’s most powerful asset and ability in the three-dimensional world. The Lord said we would be judged by every word we say. Unclean speech proves an unclean heart and also proves that the Lord Jesus is not in control. Cleansed speech proves a clean heart, but it must be emphasized that speech without bad words does not necessarily prove a clean heart or indicate the infilling of the Holy Spirit, but speech that is both clean and contains the power of God.
The early believers were speaking forth miraculous things, such as speaking languages they had never learned, prophesying through the power of God, being used in healing by speaking the Name of Jesus, and praising Him supernaturally. Their words had a powerful effect and affected great change.
Because they were filled with the Holy Spirit and the power of the Lord Jesus, they had God’s authority over all things spiritual. This is why they were able to take authority over the devil and demonic influence through the power of the Name of Jesus and work miracles. This power was granted to every member of the Lord’s community, not just the apostles. It remains available for anyone today who properly follows and obeys the Lord’s order and method of discipleship.
