And what is the prescribed response? Is it to walk down an aisle? Is it to fill out a card, or to lift up a hand? Is it to make an appointment with a preacher, or to decide to be baptized and join the church? While any of those things may be involved, none of them necessarily is. The response of the Good News – the message that Paul preached and other Christians preached throughout the New Testament – is to repent and believe. Once we’ve heard the truth about our own sin and God’s holiness, about His love in sending Christ, and about Christ’s death and resurrection for our justification, then, as instructed by the first words of Jesus recorded in Mark’s gospel, our response is to “Repent and believe the good news!” (1:15).
