When Peter was preaching during Pentecost, he told the Jewish audience that Jesus was the promised son of David, yet David’s Lord. He summed up with this “altar call”:
Acts 2:36-37 (HCSB) “Therefore let all the house of Israel know with certainty that God has made this Jesus, whom you crucified, both Lord and Messiah!” When they heard this, they came under deep conviction and said to Peter and the rest of the apostles: “Brothers, what must we do?”
His answer to their anguish was not “ask Jesus into your heart.” Acts 2:38 (HCSB) “Repent,” Peter said to them, “and be baptized, each of you, in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit.” Natural man cannot do this. MUST have the Holy Spirit indwelling a regenerated soul.
And note: repent and be baptized. Not, be sprinkled as a babe and later, if it be you are a true covenant child, repent. Repent then be baptized; this is the biblical practice.
Acts 2:39 (HCSB) “For the promise is for you and for your children, and for all who are far off, as many as the Lord our God will call.”
No matter how you interpret “the promise,” there are several views, there is no way to think the promise is to the children of Christian parents. Peter was speaking to unconverted Jews, not redeemed saints. The promise was to them – they were the ones who asked “what must we do?”
The term “brothers” in verse 37 clearly is not used in the New Covenant context, as they were at that time unconverted. Brothers in the same sense as Paul expressed agony over his “kinsmen of the flesh” – his fellow Jews. In this culture, the Jews saw themselves as the brotherhood of God against the world.
The promise to all – Jews, their children, and ALL WHO ARE FAR OFF (the Gentiles – those who, “at that time you were without the Messiah, excluded from the citizenship of Israel, and foreigners to the covenants of the promise, without hope and without God in the world.” – Eph 2:12). The promise is to the whole world, not somebody’s children – AS MANY AS THE LORD OUR GOD WILL CALL.
The promise is people in every group of people – as many as the Lord calls.
This passage no more gives support to family status in the New Covenant than it gives support to an Arminian view of salvation.
