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.

²³ But this thing I did command them: ‘Listen to and obey My voice, and I will be your God, and you shall be My people; and you will walk in all the way which I command you, so that it may be well with you.’
