We could not fully preach Christ without preaching Him as the Son of God. There are many people today who say Christians preach intolerance and promote hatred when we preach Christ as the Son of God. Why? Because this preaching is considered offensive to Jews, Muslims, Hindus, Buddhists and other religious people who do not profess Christianity.
Why did the Jews hate Christ enough to demand his death? They told Pilate, “The Jews answered him, We have a law, and by our law he ought to die, because he made himself the Son of God,” John 19:7.
Sometimes some misguided souls will tell you that Christ never claimed to be the Son of God. But, when He asked His disciples, “But whom say ye that I am?” Peter answered, “Thou art the Christ, the Son of the living God” (Matthew 16:15-16). Then Jesus said, “And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven” (Matthew 16:17).
Having made this affirmation, it seems pretty clear to Christians. He said that the Father in heaven was Peter’s source of information that He was the Christ. Mary the mother of Jesus was told by an angel “The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God” (Luke 1:35). Even unclean spirits cried out, “when they saw him, fell down before him, and cried, saying, Thou art the Son of God” Mark 3:11. Jesus said the Jews accused him of blasphemy “because I said, I am the Son of God” (John 10:36).
His resurrection declared him to be the Son of God (Romans 1:4).
Christianity stands or falls on the claim that Christ is the Son of God.
