³ I tell you, no; but unless you repent [change your old way of thinking, turn from your sinful ways and live changed lives], you will all likewise perish.

⁵ I tell you, no; but unless you repent [change your old way of thinking, turn from your sinful ways and live changed lives], you will all likewise perish.”

³ So remember and take to heart the lessons you have received and heard. Keep and obey them, and repent [change your sinful way of thinking, and demonstrate your repentance with new behavior that proves a conscious decision to turn away from sin]. So then, if you do not wake up, I will come like a thief, and you will not know at what hour I will come to you.

¹⁹ Those whom I [dearly and tenderly] love, I rebuke and discipline [showing them their faults and instructing them]; so be enthusiastic and repent [change your inner self—your old way of thinking, your sinful behavior—seek God’s will].^(A)
