There were many ways in which Jesus already revealed who He was. His miraculous works certainly revealed who He was. Jesus had also clearly revealed that He was the Christ, both in the synagogue at His hometown of Nazareth, and when speaking to the Samaritan woman at Jacob's well.
Jesus, in His pre-existent state, was in the form of God. "In the beginning was the Word and the Word was with God, and the Word was God" (Jn. 1:1).
Jesus was God, manifest in the flesh (1 Tim. 3:16). However, Jesus did not demand or cling to His rights as God, but laid aside His Divine rights and privileges in order to take the form of a servant and be made in the likeness of men. He further humbled Himself by becoming obedient to the Father, even to the point of death.
This was the supreme sacrifice that identified Jesus totally with humanity and enabled God to redeem mankind. By dying a criminal's death upon the cross, Jesus fulfilled the Old Testament prophecy in Deuteronomy 21:23 and bore our curse in His own body. This redeemed us from that curse and opened wide God's blessing of justification through faith in Christ and the promise of His Holy Spirit (Gal. 3:13-14).
Jesus left His state of being recognized and worshipped by all the hosts of heaven as the Supreme God to become a man who was despised and rejected. The Creator became the creation; the Lord became the servant; the Highest became the lowest. All of this was done because of God's great love for us.
Stewards Of God's Grace
And the Lord said, Who then is that faithful and wise steward, whom his Lord shall make ruler over his household, to give them their portion of meat in due season? Luke 12:42
A steward is a person who has been entrusted with administering someone else's wealth or affairs. The possessions a steward controls are not his own and he does not have the freedom to do with them as he wishes. He is supposed to carry out the desires of the one who made him steward.
A banker is a steward. He has been entrusted with other people's money. He is free to invest that money wisely in a way that will benefit his depositors and stockholders, but would be sent to jail if he took all that money and simply consumed it upon himself. A steward is accountable (Lk. 16:2) to someone else for the use of that person's money. The money does not belong to him even though it is in his possession.
