Faith, was something that was spoke of to the Gentiles. Repentance was spoken to the nation of Israel, for having delivered the Son of God over to be killed, and also worshipping the Law over God himself. What was the reason of repenting for the lands of Israel in that day? To be saved from Gods Wrath when it fell upon that nation and it went up in blazing fire. Today it is one of faith, faith has to come first. Just saying "repent because God doesn't love you unless you do not, and you are going to be in hell forever" Is a false message. God so loved the world, he gave his only begotten son. When faith is instilled, then perhaps comes growth, and perhaps a change of mind may come as well, but faith on the Son of God, including his resurrection is something that must come first. Unless it someone out there that doesn't know these things, but they look to faith towards God I believe he is still able to reach those people by the holy spirit and by writing on their minds and hearts. Though most see that as just to far.
