(1Co 1:22) “For the Jews require a sign, and the Greeks seek after wisdom: (23) But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness;” The Jews had received their sign, the sign of Scripture fulfilled. Jesus had performed miracles among them and even rose from the dead – all in fulfillment of Scripture. Even to that day they were being given a period of grace as God continued to demonstrate miraculous miracles through the Holy Spirit.
