Lord’s Library editors offer this Acts 2:21 meaning with commentary and supporting Scriptures for your edification.
To obtain an Acts 2:21 meaning, first see the verse: “And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.” This statement, first spoken by the prophet Joel and quoted by the Apostle Peter on the Day of Pentecost, is the foundational Gospel truth: salvation is freely available to “whosoever” will believe, and it is obtained by calling upon the name of the Lord Jesus Christ in faith.
This “calling” is a legitimate and heartfelt cry of trust in the Finished Work of Jesus Christ—His death, burial, and resurrection—as the only means of redemption. Acts 2:21 encapsulates the Gospel of grace: salvation cannot be earned by righteous works of the law, and is imputed by grace through faith alone.
The context of Acts 2 is crucial to understanding the depth of this verse. Peter is preaching to a crowd in Jerusalem shortly after the Holy Spirit was poured out on the disciples. He proclaims the risen Christ, crucified according to God’s plan, and calls on all to repent and believe the Gospel.
He cites Joel to demonstrate that what the people are witnessing is the fulfillment of prophecy. But within that citation is the timeless promise of salvation: “whosoever shall call on the name of the Lord shall be saved.” This statement opens the door of salvation to all people—Jews and Gentiles alike—and reveals the inclusiveness of the Gospel message.
The Apostle Paul later explains it in Romans 10:12–13: “For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. For whosoever shall call upon the name of the Lord shall be saved.”
Acts 2:21 Meaning
Calling on the name of the Lord implies faith over deeds; it is the outward expression of inward belief. Romans 10:9–10 explains it: “That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.”
This portrays heart-level belief in the death and resurrection of Jesus Christ—His finished Work on the Cross—and is what saves the sinner. Christ Himself said in John 5:24: “Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.”
The Gospel of Jesus Christ is centered on the truth that He died for our sins, was buried, and rose again on the third day, according to the Scriptures. See 1 Corinthians 15:1–4: “Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:”
It is this Blood Atonement that satisfies the justice of God and makes forgiveness available. See Ephesians 1:7: “In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace;”
And see next Colossians 1:14: “In whom we have redemption through his blood, even the forgiveness of sins:” As one can see clearly, salvation is not something that can be classically “achieved”; it is something we receive by faith. Ephesians 2:8–9 makes it clear: “For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.”
Acts 2:21 also reveals the sufficiency of Christ. It is not Christ plus the law, Christ plus good works, or Christ plus sacraments; it is Christ alone. See Peter’s words in Acts 4:12, “Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.”
John 14:6 makes reference to Jesus as the only way, the only truth, and the only life: “Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.”
This is the gracious message of the Gospel: all are sinners, all are under the just condemnation of God (Romans 6:23), but all may be justified freely by His grace through the redemption that is in Christ Jesus. See Romans 3:23, Romans 6:23, and Romans 3:24:
- Romans 3:23: “For all have sinned, and come short of the glory of God;”
- Romans 6:23: “For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.”
- Romans 3:24: “Being justified freely by his grace through the redemption that is in Christ Jesus:”
To call on the name of the Lord is to believe the Gospel and trust Him fully. It is an act of faith that acknowledges personal sin, the sufficiency of Christ’s Atonement, and the need for mercy; man’s only hope. The Philippian jailer asked Paul and Silas, “What must I do to be saved?”
The answer was simple and direct: “Believe on the Lord Jesus Christ, and thou shalt be saved.” See Acts 16:30-31: “And brought them out, and said, Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.”
This belief is the abandonment of all self-reliance and the full dependence on Jesus Christ and His shed blood.
