Jesus is the Son of God, the Son of David, and the Son of Man.
Jesus is both eternal God, and perfect human.
Son of God
Jesus, the Word, is eternal, was God in the beginning, and was with God in the beginning. (John 1:1)
All things came into being through Jesus, the Son of God. (John 1:3)
Son of David
The Son of David was prophesized many years before His birth.
I will raise up your descendant after you [David], who will come forth from you, and I will establish his kingdom. He shall build a house for My name, and I will establish the throne of his kingdom forever. (2 Samuel 7:12–13)
For today in the city of David there has been born for you a Savior, who is Christ the Lord. (Luke 2:11)
Son of Man
Behold, with the clouds of heaven One like a Son of Man was coming, and He came up to the Ancient of Days And was presented before Him. And to Him was given dominion, Glory and a kingdom, that all the peoples, nations and men of every language might serve Him. His dominion is an everlasting dominion which will not pass away; And His kingdom is one which will not be destroyed. (Daniel 7:13–14)
Jesus referred to Himself most often as the Son of Man.
The Son of Man has authority on earth to forgive sins. (Matthew 9:6)
The Son of Man is Lord of the Sabbath. (Matthew 12:8)
The Son of Man came to save that which was lost. (Matthew 18:11)
The Son of Man came to serve. (Mark 10:45)
Just as the Father has life in Himself, even so He gave to the Son also to have life in Himself; and He gave Him authority to execute judgment, because He is the Son of Man. (John 5:25–27)
Jesus, the Son
He lived a perfect, righteous life, and gave Himself as the perfect sacrifice to save us, believers, from our sins.
He lives at the right hand of God, always interceding for us as our great High Priest.
He will come again, with glory, to rule as King of kings and Lord of lords.
Praise the Son
I praise You, Christ Jesus, Son of God, Son of David, Son of Man. You, Son of God, humbled Yourself to be born as the Son of David, and humbled Yourself as the perfect sacrifice to save us. You, the Son of Man, have an everlasting kingdom. Thank You for ever interceding for Your flock. I praise You, our almighty, holy, ruler. Come, Lord Jesus.
