In Matthew, we read “Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.” (1:18)
There is no doubt that Jesus is a man. The genealogies prove that. He is a descendant of Abraham through David. Jesus was as human as we are. But what about this “child of the Holy Ghost”? No one in the whole history of the human race was conceived this way. Who is Jesus Christ?
Gabriel, the angel of God, appears to announce the birth of Jesus to Mary. (Luke 1:30-33). One of the most astonishing things that he said was that the child was to be the Son of the Most High. The child’s Father would be God Himself, for Jesus would be the “Son of the Most High.”
The whole New Testament picks up this title and explains it.
Peter’s confession is one example. Jesus had asked his disciples who they thought He was, and Peter replied, “You are the Christ, the Son of the living God” (Matt. 16:16).
This was no mere earthly sonship for Jesus indicated that Peter’s insight was so remarkable that it had come not from Peter’s own powers of observation but by revelation from God. (v. 17)
In 1 John we find the fullest New Testament treatment on the matter. The Christians to whom John wrote had been shaken by teachers who claimed to be believers who were denying that Jesus was “God . . . Come in the flesh” (1 John 4:2-3) John wrote to assure them: “If anyone acknowledges that Jesus is the Son of God, God lives in him and he in God. And so we know and rely on the love God has for us (1 John 4:15-16)
Christians can know they are of God by their conviction that Jesus is indeed God’s Son. “Jesus is the Son of God” becomes the confession by which one can tell whether or not one is actually a Christian.
When Gabriel told Mary that the future child would be “the son of the most High,” he was saying that the child would be God. Jesus is God!
