Christ is the incarnate Son of man, He is the Spirit of God clothed in flesh and He is God Himself, who can express the truth and provide man with life.
When the incarnate Lord Jesus came to do the work of redemption of mankind, God became the Son of man, appearing and doing work among men. He not only opened the Age of Grace, but also initiated a new age in which God came personally into the human world to live alongside man.
“Philip said to him, Lord, show us the Father, and it suffises us. Jesus said to him, Have I been so long time with you, and yet have you not known me, Philip? he that has seen me has seen the Father; and how say you then, Show us the Father? Believe you not that I am in the Father, and the Father in me?
The Lord Jesus Christ initiated the Age of Grace and concluded the Age of Law. He brought the people of the Age of Grace new means of practice through delivering the truth and spreading the way of repentance.
