We have seen three different times in the Old Testament where someone is called the son of God. Adam was the son of God. The people of Israel under Moses were the son of God. And the son of David, the one who would be king, was the son of God.
Now we come to the gospel (the injil) where we read that Jesus is the son of God. We can’t say too often that God did not have relations with Maryam and make her pregnant. Such a thought truly is blasphemy.
We first see that Jesus Christ is the son of God when the angel announced his birth, “He will be great and will be called the Son of the Most High. And the Lord God will give to him the throne of his father David, and he will reign over the house of Jacob forever, and of his kingdom there will be no end” (Luke 1:32-33). It is declared at his baptism, “And behold, a voice from heaven said, ‘This is my beloved Son, with whom I am well-pleased” (Matthew 3:17). It is then stated again at the transfiguration, but this time something is added, “He was still speaking when, behold, a bright cloud overshadowed them, and a voice from the cloud said, “This is my beloved Son, with whom I am well pleased; listen to him.” (Matthew 17:5).
Ultimately, Jesus is declared, confirmed, and installed as the Son of God at his resurrection. “And we bring you the good news that what God promised to the fathers, this he has fulfilled to us their children by raising Jesus, as also it is written in the second Psalm, “‘You are my Son, today I have begotten you.’ And as for the fact that he raised him from the dead, no more to return to corruption, he has spoken in this way, “‘I will give you the holy and sure blessings of David’” (Acts 13:32-34).
Jesus Christ is the true son of God. The Injil teaches that he is the second Adam, the son of God who is the head of his people (“Thus it is written, ‘The first man Adam became a living being’; the last Adam became a life-giving spirit” [1 Corinthians 15:45], see also Romans 5:14-21). But unlike Adam, Jesus Christ obeyed God in everything.
Jesus Christ is the true Israel, the son of God. In the Injil we read about Jesus Christ being tempted in the wilderness for forty days just like Israel wandered in the wilderness forty years (see Matthew 4:1-11). But unlike Israel, Jesus Christ obeyed God in everything.
Jesus Christ is the son of David, the son of God. He is descended from David and is the Christ. The Messiah (Christ means Messiah) is the one who is God’s anointed king, the one God promised to be ruler over his people (“concerning his Son, who was descended from David according to the flesh and was declared to be the Son of God in power according to the Spirit of holiness by his resurrection from the dead, Jesus Christ our Lord” [Romans 1:3-4]). Unlike Solomon and the other sons of David, Jesus Christ obeyed God in everything.
Jesus Christ is the true Son of God because he is the last Adam, the true Israel and the son of David. To say that Jesus is the son of God we are saying that he is the Messiah. We are saying that he is God’s king who will rule over God’s people.
