Acts 2
22 “Men of Israel, hear these words: Jesus of Nazareth, a Man attested by God to you by miracles, wonders, and signs which God did through Him in your midst, as you yourselves also know— 23 Him, being delivered by the determined purpose and foreknowledge of God, you [f]have taken by lawless hands, have crucified, and put to death; 24 whom God raised up, having [g]loosed the [h]pains of death, because it was not possible that He should be held by it.

From my commentary:
Peter did not flinch at saying, “You crucified this Man who God sent.” His first concern was not to please his audience, but to tell them the truth. The Spirit-filled Peter was a different man than the Peter who, a few months before this, denied even knowing Jesus.

Peter was preaching Christ crucified with a renewed mind and a Holy Spirit filling. This is a guarantee for the seeds of truth to be planted.
