Since Christianity is the only faith that worships Jesus as God, this passage is used by cults and other religions to deny His deity. Actually, Jesus is fully God and fully man, an idea supported in scripture. For instance, the book of John is filled with references to show how Jesus is God (e.g., John 1:1, 14; 8:58; 10:30; 14:6; 20:28).
But Jesus was also man (e.g., Col 2:9; 1 Tim 2:5; 1 John 4:2-3). To explain this apparent contradiction, theologians use the term “hypostatic union,” which means Jesus had two natures in one body. Jesus humbled Himself by taking “on the likeness of men,” even experiencing “death on a cross.” Through all of this, Jesus never lost His deity.
This can be shown to be true in verse 10, which promises how “every knee should bow” and “every tongue should confess” that Jesus is Lord. If Jesus were not God, then worshiping Him would be blasphemous.
