'Repent' in the Bible

“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.”

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.”

Then He began to denounce [the people in] the cities in which most of His miracles were done, because they did not repent [and change their hearts and lives].

and said, “I assure you and most solemnly say to you, unless you repent [that is, change your inner self—your old way of thinking, live changed lives] and become like children [trusting, humble, and forgiving], you will never enter the kingdom of heaven.
