Rev. 2:18 And unto the angel of the church in Thyatira write; These things saith the Son of God, who hath his eyes like unto a flame of fire, and his feet are like fine brass;
In this passage we see Jesus, not as the Son of man, but as the Son of God. This is his true nature, his innate being, his sovereign existence. As the Son of God he has always existed, and he shall always exist even throughout the eternal ages.
Even the centurion, who saw Jesus on the cross dying a horrible death, after hearing the enemies of the Lord chide him about being the Son of God, tempting him to come down from the cross to prove his deity, the centurion nonetheless said, Truly this man was the Son of God (Mark 15:39). If this centurion can see that Jesus was the Son of God, certainly it seems that many others can also see that he is the Son of God.
He is God's beloved Son (Mark 3:17). He is the only begotten Son of God (John 3:16, 18). He is the crucified Son of God (Heb. 6:6). He is the Son who must be believed, 1 John 5:10 He that believeth on the Son of God hath the witness in himself: he that believeth not God hath made him a liar; because he believeth not the record that God gave of his Son.
The Ethiopian Eunuch put his complete faith in Jesus as the Son of God in Acts 8:37 And Philip said, If thou believest with all thine heart, thou mayest. And he answered and said, I believe that Jesus Christ is the Son of God.
But Jesus had to be both Son of God and Son of man before he could reconcile God and man. He must touch the presence of God in a real way, be as God is, understand the delicacies of the Father's wisdom and power and preview all things from Heaven's view. Then he must, by his own contract with God, submit to come to earth and die for the sins of his people. This is a great mystery and one which no man can understand, but it is nevertheless true. Jesus was incarnated (put in the flesh) that he might experience not only God's view of things but man's view of things. He must be tempted in all points like as we are (Heb. 4:15); he must suffer as a servant (Isaiah 53:11); he must lie in the tomb three days and three nights (Matt 12:40); and he must arise from the dead Matt 17:23 And they shall kill him, and the third day he shall be raised again. And they were exceeding sorry.
Let us see Jesus as the Son of man, dealing with sin (Rom. 8:3), feeling our infirmities as our High Priest (Heb. 4:15), and dying for us personally and individually (1 Cor. 15:3). But we must see Jesus as the Son of God, majestic, holy, perfect, righteous, sovereign, a revealer of truth and the delineation of the word of God. We must see him on the throne sitting at the Father's right hand and coming in the clouds of Heaven (Matt. 26:64).
He served here as the Son of man, but one day he will come as the Son of God with fiery judgment upon those who are his enemies, those who do not trust in his sacrificial work on the cross, the shedding of his precious blood for the remission of sins of those who will come to him by faith.
