Mark 1:14-15

Now after John [the Baptist] was arrested and taken into custody, Jesus went to Galilee, preaching the good news of [the kingdom of] God, and saying, “The [appointed period of] time is fulfilled, and the kingdom of God is at hand; repent [change your inner self—your old way of thinking, regret past sins, live your life in a way that proves repentance; seek God’s purpose for your life] and believe [with a deep, abiding trust] in the good news [regarding salvation].”
