Jesus never had any question about what His purpose was here on earth. This was decided before the beginning, He had laid aside all of His royalty in heaven and come to earth as Love incarnate. He lived a simple life doing what He saw the Father do and saying what the Father said. Now, the time for Him to return to His glory in Heaven was quickly approaching. He loved people with a love that our human minds cannot fully embrace. Even knowing that Judas would betray Him, He allowed Judas to be one of His disciples. The Father had given Him all authority over all things and He could have used it at any time. Yet, He stayed the course and died a cruel death for our redemption. He was love clothed in human flesh for our benefit. Through the blood of Jesus, we have access to that same love. Jesus was perfect and could love perfectly, we are imperfect and so we love imperfectly. But one day, we will love as He loves. Then we will know fully just as God knows us now. We need to practice showing love to others every day so they will be attracted to Jesus. Love will never fail.
12 It is the same with us. Now we see a dim reflection, as if we were looking into a mirror, but then we shall see clearly. Now I know only a part, but then I will know fully, as God has known me. 13 So these three things continue forever: faith, hope, and love. And the greatest of these is love.–1 Cor. 13:12,13 (NCV)
