Luke 24:47-this is AFTER Jesus died on the cross; just before his ascension into heaven. He told his disciples that “repentance and remission of sins would be preached “to all nations” BEGINNING at Jerusalem. They were instructed to “wait in Jerusalem”. for the Holy Spirit which they would receive from on high.
50 days later, there are Jews at Jerusalem “from every nation under heaven”; the Holy Spirit is poured out on the disciples and Peter tells the Jews to “REPENT and be baptized …For The REMISSION of SINS.” This was the “beginning” that Jesus was talking about in Luke 24. It was not preached before that day. The thieves had been dead for over a month.

“Therefore we must pay much closer attention to what we have heard, lest we drift away from it. For since the message declared by angels proved to be reliable, and every transgression or disobedience received a just retribution, how shall we escape if we neglect such a great salvation? It was declared at first by the Lord, and it was attested to us by those who heard, while God also bore witness by signs and wonders and various miracles and by gifts of the Holy Spirit distributed according to his will.”
