Jesus is of the essence of God — in existence, goals, methods, concepts, etc. What Jesus is, God is — so Jesus is an example of what God is.
You believe in Jesus because you believe in God!
God knows more than Jesus [such as when it is time for the Second Coming]. God is Supreme and Jesus said to ALWAYS worship, glorify, follow, trust, and obey God as well as to pray to God alone! Jesus followed God’s plan even to death, resurrection, interceding, and beyond!
