Matthew 28:18 And Jesus came and spoke to them, saying, “All authority has been given to Me in heaven and on earth.
Christ did not come out of the grave telling everyone He was higher than God because He had personally defeated death; instead Jesus declared God the Father had given Him all power.
Jesus is part of the God-Head and not God by Himself. God the Father, God the Son (Jesus) and God the Holy Spirit make up what we know as God.
It is difficult for us to understand and gets in our way of learning when we get bogged down in trying to understand.
Simply believe the words Christ told us and trust fully in Him!
