It is important to observe that “Son of God” when it is applied to Jesus means something quite different from “sons of God” elsewhere in Scripture (e.g., Job 1:6; Mat. 5:9; Rom. 8:14). So how is Jesus’ identity as the Son of God unique?
Our Lord refers to himself as the Son
“No one knows the Father except the Son and anyone to whom the Son chooses to reveal him” (Mat. 11:27).
The Scriptures refer to Jesus as the only Son
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life” (John 3:16).
There is a great difference between the sonship of Jesus, who has always been the Son of God by nature, and the way in which we become the children of God through adoption by grace: “To all who did receive him … he gave the right to become children of God” (John 1:12).
The Son of God is “God with us”
John tells us that “the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father” (John 1:14). The Son is the Word of God made flesh. God himself became man.
The book of Hebrews says of God’s Son that “he is the radiance of the glory of God and the exact imprint of his nature” (Heb. 1:3). The sun and its radiance are inseparable. There is no sun without the radiance and there is no radiance without the sun. Jesus Christ, the Son of God, is the radiance of God’s glory. He is the outpouring of all that God is. He is God with us.
In what ways do you see God’s glory revealed in Jesus as the unique Son of God?
