The fundamental teaching of the Bible, God's revelation to man, is that Jesus is the Son of God. It is the basis of the New Testament Scriptures (John 20:30-31) and the theme of New Testament preaching (See Acts 2:36; 17:1-3; 1 Corinthians 2:2). The Scriptures contain many facts that give positive evidence to support its main theme.
Consider what they reveal about the life of Jesus. They show He had an immeasurable influence on people, that His teachings were the greatest words ever spoken (John 7:44-46) and that His life was sinless (Hebrews 4:15; 1 Peter 2:21-22; John 8:46). Even the enemies of Jesus admitted His innocence (Acts 2). Compare His sinlessness to the rest of mankind and you will find Him to be the only one ever to live in sinless perfection (Romans 3:10, 23).
Consider also what the Scriptures say about the miraculous works Jesus performed. Those works, done by the power of God (John 3:2), gave evidence that He was from the Father and gave support to His claim to be the Son of God (John 5:36). No one, not even those who opposed Him, ever denied His ability to work miracles. They may have attributed the power to work them to an evil source but they could not deny that He worked wonders before them.
The Scriptures also tell how Jesus fulfilled every one of the more than 300 Messianic prophecies of the Old Testament. He used those prophecies to further establish and confirm His identity (Luke 24:25-27; John 5:39-40). It would have been impossible for an impostor to manipulate events and occurences in such a way as to appear to be the genuine fulfillment of these prophecies. Many of the prophecies were minute in their details. Others were impossible for a human to control.
Among those Old Testament prophecies was the prophecy of the resurrection of the Messiah from the dead (Psalm 16:10). The resurrection is the greatest evidence the Scriptures give in support of Jesus as the Son of God. If one accepts His resurrection as true, there can be no question of His divinity. Romans 1:4 says that the resurrection demonstrated to all that He is the "Son of God with power." Though efforts have been made to explain it away, the resurrection of Jesus Christ from the dead is an undeniable fact. It shows without doubt that the basic message of the Bible is true -- Jesus Christ is the Son of God.
