Matthew 4:17, 23

From that time Jesus began to preach and say, “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], for the kingdom of heaven is at hand.”

And He went throughout all Galilee, teaching in their synagogues and preaching the good news (gospel) of the kingdom, and healing every kind of disease and every kind of sickness among the people [demonstrating and revealing that He was indeed the promised Messiah].
