okay, no harm done. But you know preaching the Gospel is a ongoing activity, its also spiritual food. When Jesus told Peter to feed His Lambs and sheep, that began on the day of pentecost with the Gospel. In Peters first sermon he preached preached a form of predestination Acts 2:23
23 Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain:
He came again Acts 4:27-28
27 For of a truth against thy holy child Jesus, whom thou hast anointed, both Herod, and Pontius Pilate, with the Gentiles, and the people of Israel, were gathered together,
28 ;For to do whatsoever thy hand and thy counsel determined before to be done.
He preached the effectual call Acts 2:39
39 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.
He preached particular atonement, for he directed his message about Christ to a particular people Acts 2:36
36 Therefore let all the house of Israel know assuredly, that God hath made the same Jesus, whom ye have crucified, both Lord and Christ.
