“I will proclaim the decree of the Lord: He said to me, ‘You are my Son; today I have become your Father’.” Psalm 2:7, NIV. David was a shepherd, a warrior, a musician, a poet, and a king. Many unique experiences filled his life. However, through it all, he learned that relying on the Lord was the only answer. He was also fully aware that humankind needs a Savior. God loved David, and He promised that through his descendants Savior of the world, the Messiah, will come. Accordingly, David channeled his poetic talent in writing about the promised Messiah, the Lord. In the above verse, David refers to the Messiah, the Son of God. Apostle Paul, in the Hebrews 5:5, applies the Psalm 2:7 to the Son of God and the Son of man, Jesus Christ.
God, through the prophet Ezekiel, promised to give the fallen humankind a “new spirit,” a new life. Ezekiel 36:26. The spirit which God put into humankind at creation sinned and, therefore, it had to die the eternal death, no way out. At the incarnation, God gave the fallen humanity a new spirit, the spirit of Jesus Christ, which is from God, not from man. “The angel answered, ‘The Holy Spirit will come upon you, and the power of the Most High will overshadow you. So the holy one to be born will be called the Son of God’.” Luke 1:35, NIV. The new spirit, the new life of the humankind, came from God, but the body of Jesus was through Mary, a human being. Because the new spirit came from God the Creator, Jesus, as the representative of the new humankind God created at the incarnation, was the Son of God in same sense the first Man, Adam, was the son of God. Luke 3:37 – 38, NIV.
The first representative of the humankind, Adam, sinned, and had to die forever. “So it is written: ‘The first man Adam became a living being’; the last Adam, a life-giving spirit.” 1 Corinthians 15:45, NIV. Apostle John agrees, “In him was life, and that life was the light of men.” John 1:4, NIV. By taking on Him the human body, the “life-giving spirit”, Jesus, gave to “all who believed in his name,” the right to be a child of God. John 1:12, NIV.
