Scripture represents the Lord Jesus Christ, in all that He did and suffered for His people, as fulfilling the terms of a gracious compact or arrangement which He had entered into with His heavenly Father before the foundation of the world.
1. Jesus was sent into the world by the Father to save the people whom the Father had given to Him. Those given to Him by the Father come to Him (see and believe in Him), and none of them shall be lost. (John 6:35-40)
2. Jesus, as the good shepherd, lays down His life for His sheep. All who are "His sheep" are brought by Him into the fold and are made to hear His voice and follow Him. Notice that the Father had given the sheep to Christ! (John 10:11, 14-18, 24-29)
3. Jesus, in His High Priestly Prayer, prays not for the world, but for those given to Him by the Father. In fulfillment of the Father's charge, Jesus had accomplished the work the Father had sent Him to do - to make God known to His people and to give them eternal life. (John 17:1-11, 20, 24-26)
