“If Christians are forgiven, and they know they will be forgiven no matter what they do, why should they refrain from doing evil?”
Jesus warned his disciples from the very beginning of his ministry on earth to expect that there would be counterfeits among their number. The apostle John writes about what happened when Jesus began to perform miracles in Jerusalem at the Passover. He says, “Many believed in his name.” Then he adds this: “But Jesus on his part did not entrust himself to them, because he knew all people and needed no one to bear witness about man, for he himself knew what was in man.” Some of these “believers” were not genuine in their desire to associate themselves with him, and would later fall away.
