Mark 1:13-15

13 He was in the wilderness forty days being tempted [to do evil] by Satan; and He was with the wild animals, and the angels ministered continually to Him.

14 Now after John [the Baptist] was arrested and[9] taken into custody, Jesus went to Galilee, preaching the good news of [the kingdom of] God,

15 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]."
