“Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ. Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do? Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call. And with many other words did he testify and exhort, saying, Save yourselves from this untoward generation. Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls. And they continued stedfastly in the apostles’ doctrine and fellowship, and in breaking of bread, and in prayers.” Acts 2:36-42 (Read Acts 2)
A piercing truth often comes with a painful sting. We tend to trust those in authority, particularly in matters of faith. We rely on our religious leaders, our church bodies, and the traditions we’ve inherited, often without questioning whether they align with divine truth revealed in the Bible. Yet, the story of Peter’s sermon on the Day of Pentecost, recorded in Acts 2, serves as a powerful reminder that even deeply religious people, led by their trusted guides, can tragically miss God’s clearest revelation. It also shows us the path back to Him when that painful truth is revealed.
Peter, filled with the Holy Ghost, stood before a crowd of devout Jews gathered in Jerusalem for the feast of Pentecost. He didn’t mince words. He declared that the very Jesus, whom they and their religious leaders had rejected and crucified, God had made “both Lord and Christ” (Acts 2:36).
This was a gut-wrenching revelation. Imagine the guilt, the shame, the profound realization that they had participated, however unknowingly, in the rejection and murder of their long-awaited Messiah. Their hearts were “pricked,” pierced by the weight of their grave error. Their immediate, desperate cry was, “Men and brethren, what shall we do?” (Acts 2:37).
Peter’s answer was direct and to the point. He didn’t offer complicated rituals or lengthy penance. He laid out a clear path to reconciliation with God and new life: “Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call” (Acts 2:38-39). Furthermore, he exhorted them, saying, “Save yourselves from this untoward generation” (Acts 2:40).
This ancient account remains profoundly relevant to us today. Just as those in Peter’s audience, we too can find ourselves blindly following our church bodies and religious leaders, even when they lead us astray. History is replete with examples of religious institutions falling into error, embracing doctrines or practices that deviate from God’s Word. Our comfort in tradition or our loyalty to a particular denomination can sometimes overshadow our personal responsibility to discern truth. When we encounter a truth that challenges our long-held beliefs or exposes an error within our spiritual landscape, the question that should echo in our hearts is the same as that of Peter’s hearers: “What shall we do?”
Peter’s words offer the timeless answer. First, repent. This is not merely feeling sorry for ourselves; it’s acknowledging our error, turning from it, and looking to God in faith for mercy and forgiveness in His Son, Jesus Christ.
Second, we are to be baptized, every one of us, in the name of Jesus Christ for the remission of sins (cf. Matt. 28:18-20). Baptism signifies our union with Jesus Christ and our participation by faith in the new covenant He established through the shedding of His holy and precious blood on the cross (cf. Col. 2:11-15; Jer. 31:31-34; Heb. 8:6ff.; 9:11ff.; Mark 16:16; John 3:14-18). It signifies our union with Christ in His death for our sins, that, as Christ was raised from the dead, we should be raised up in newness of life, alive to God through faith in Christ Jesus (cf. Rom. 6:3-4; Gal. 3:26-29). It signifies the washing away of our sins and guilt and a new identification in Christ (cf. Acts 22:16).
Third, Peter promised the gift of the Holy Spirit, who would indwell believers and guide them into all truth by giving them a right understanding of the Scriptures. This promise, Peter emphatically stated, “is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.” It’s a universal invitation, extending to every generation and every person God draws to Himself.
Finally, the call to “save yourselves from this untoward generation” is a summons to separate ourselves from the prevailing attitudes, values, and errors of the world around us — even from religious distortions — and to turn to Jesus, the Christ, who is “the way, the truth, and the life” (John 14:6).
The immediate response of three thousand souls on that day was a testament to the power of God’s truth. They “gladly received his word” and were baptized (Acts 2:41). Their conversion was not a superficial experience; they “continued stedfastly in the apostles’ doctrine and fellowship, and in breaking of bread, and in prayers” (Acts 2:42). Their lives were profoundly reshaped by their encounter with the resurrected Lord and the truth of God’s Word made known to them through the preaching of Peter.
Let us, then, examine our own hearts and the spiritual paths we walk. Are we diligently seeking God’s truth, even if it challenges our comfort zones or familiar traditions? Are we willing to repent when the Holy Spirit convicts us of error, regardless of how deeply ingrained it may be within our religious upbringing? The path Peter laid out is not just for a crowd in Jerusalem two millennia ago; it is God’s enduring invitation to us. It is the way to reconciliation, forgiveness, the empowering presence of the Holy Spirit, and true fellowship with Christ. May we respond with the same earnestness as those on Pentecost, and find our salvation in Christ Jesus alone!
Have mercy upon me, O God, and forgive my sins, which caused the innocent sufferings and death of Christ Jesus, Your Son, and my Savior. Join me to Christ Jesus in my baptism and make the forgiveness and life He won for me on the cross my own through faith in His name. And grant me Your Holy Spirit and teach and guide me with Your Word, keeping me in the true faith unto life everlasting. In Jesus’ name, I pray. Amen.

O almighty God — Father, Son, and Holy Spirit — we come into Your presence to seek Your mercy, to hear Your Word, and to offer up to You our prayers and praises. Hear us for the sake of the Son, our Lord Jesus Christ, and His atoning sacrifice on the cross for our sins. Amen.
Psalm 32 A Psalm of David, Maschil.
Blessed is he whose transgression is forgiven, whose sin is covered. Blessed is the man unto whom the LORD imputeth not iniquity, and in whose spirit there is no guile. When I kept silence, my bones waxed old through my roaring all the day long. For day and night thy hand was heavy upon me: my moisture is turned into the drought of summer. Selah.
I acknowledged my sin unto thee, and mine iniquity have I not hid. I said, I will confess my transgressions unto the LORD; and thou forgavest the iniquity of my sin. Selah.
For this shall every one that is godly pray unto thee in a time when thou mayest be found: surely in the floods of great waters they shall not come nigh unto him. Thou art my hiding place; thou shalt preserve me from trouble; thou shalt compass me about with songs of deliverance. Selah.
I will instruct thee and teach thee in the way which thou shalt go: I will guide thee with mine eye. Be ye not as the horse, or as the mule, which have no understanding: whose mouth must be held in with bit and bridle, lest they come near unto thee. Many sorrows shall be to the wicked: but he that trusteth in the LORD, mercy shall compass him about. Be glad in the LORD, and rejoice, ye righteous: and shout for joy, all ye that are upright in heart.
Confession of Sins
P: Let us confess our sins unto the Lord our God and look to Him for mercy and forgiveness for the sake of the plenteous redemption accomplished by Jesus Christ, who has redeemed us from all our iniquities.
C: Almighty God, our Maker and Redeemer, we poor sinners confess to You that we are by nature sinful and unclean and that we have sinned against You in our thoughts, desires, words, and deeds. We, therefore, flee for refuge to Your infinite mercy, seeking and imploring Your grace for the sake of our Lord Jesus Christ.
P: For the sake of Jesus’ holy life, His atoning sacrifice on the cross, and His glorious resurrection and ascension, I announce unto you the grace and mercy of God and proclaim to you forgiveness for all your sins through faith in Jesus’ name. Amen.
