How did John become the disciple Jesus loved? Through John believing it. The Agape of Jesus believed by John made him the disciple Jesus loved. Why did Jesus ask Peter do you love (agape) me? because he wanted to see if Peter believed that Jesus loved (agaped) him regardless of what he had done.
This is vital truth for those sealed under the Third Angel. Do you know that Jesus Agapes you despite what you have done in the past? Do you believe in His forgiveness and power to sin no more?
