JOHN 5:28-47
This is referring to the fact that Jesus came in the power and authority of His father to point men to Father God. Jesus existed before His coming to this earth in the form of God and was equal with God. He humbled Himself and became a servant while here on earth (Philippians 2:6-8).
He did not come to promote Himself but to give His life to provide the way to the Father (John14:6). In the same way, the Holy Spirit does not promote Himself, but points all men to Jesus. Jesus came, meek and lowly, totally submitted unto, and seeking only to please, the Father.
This is really different from the way "great men" present themselves. The Roman Caesar of Jesus' day proclaimed that he was God and demanded worship. Lesser leaders ruled by exalting themselves over the people they governed; but, Jesus showed us that "whosoever will be great among you, let him be your minister; and whosoever will be chief among you, let him be your servant: even as the Son of man came not to be ministered unto, but to minister, and to give his life a ransom for many" (Matthew 20:26-28).
If we are concerned about what people think, we will never take a stand in faith for anything that might be criticized. This one thing has probably stopped as many people from receiving from God as anything else. We cannot be a "man-pleaser" and please God at the same time.
Commit all to Him - every thought, word, and deed.
