A confusing aspect of Jesus’ sacrifice for many people is His submission to the Father as a servant. Although Jesus is spoken of as equal to God in every regard, when He came to earth as the Messiah, He set aside some of His rights as God to become the servant, whom Isaiah 53 describes.
Philippians 2:5-8 Let this mind be in you which was also in Christ Jesus, 6 who, being in the form of God, did not consider it robbery to be equal with God, 7 but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. 8 And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross.
At no time did Jesus ever cease to be God while He was here on earth in the form of a man. He did, however, choose to make Himself of no reputation and take the form of a servant for our benefit. This is stunning when we consider who Jesus has been prior to His appearance on earth as our Savior. The Bible describes Jesus as the second member of the Godhead who spoke the universe into existence (Colossians 1:16-17). He has no beginning; and He is the one to whom all glory, honor, power and dominion are ascribed to by the Bible.
