Jesus Proclaimed Himself to be both the Son of God and the Son of Man, these two go hand in hand as the Son of Man He was fully Human, as the Son of God He was proclaiming Himself fully God. This has been and forever will be the test of the spirit in the person claiming to be a Christian. By Being the Son of God, Jesus is saying He is distinct from the Father, But at the same time He says I and my Father are one. (John 10:30) The immediate reaction of the Jews was to take up stones and stone him "because thou, being a man, makest thyself God." (John 10:33) So the Jews knew His claim to be the Son of God and His proclamation of oneness with the Father, meant he was claiming to be God, and that very belief is the essence of Christian faith. So to truly Believe that Jesus is the Son of God is to declare that he is God, because he and the Father are one. To proclaim and believe he is the Son of Man is to believe he was fully Human.... Denying one or the other of these facts fails the test of the spirit in us, and we all need to re-examine what spirit it is that controls us, Because the Holy Spirit bears witness in our lives of these facts. Not a lesser God, or demi-god like Tammuz..... we do not worship Tammuz, we worship the Only Begotten Son of God.
Therefore the Jews sought the more to kill him, because he not only had broken the sabbath, but said also that God was his Father, making himself equal with God. (John 5:18)
