Let him turn away from wickedness and shun it, and let him do right. Let him search for peace (harmony; undisturbedness from fears, agitating passions, and moral conflicts) and seek it eagerly. [Do not merely desire peaceful relations with God, with your fellowmen, and with yourself, but pursue, go after them!] —1 Peter 3:11
Paul said, “I want to do what is right, but I can’t” (see Romans 7:15-25). He was a new person on the inside because he was born again, but he still had to resist the temptation to sin.
Paul explained that “the sin [principle]” (v. 20) continues to dwell in us. We want to do right, but we don’t have the power to perform it, because evil is ever present to tempt us to do wrong. Only God can deliver us from this tendency to sin; that is why we must ask Him to deliver us from evil each day.
