Why is the Deity of Jesus Christ So Important?

In the minds of many people God is a distant, foreign, indescribable entity that exists out there somewhere. They claim to believe in God but pay little attention to Him and don’t want to be subject to Him. Their god is expected to help them when they need it but never make them feel convicted or guilty of sin.
In addition, many people who say they believe in God do not believe in Jesus. This is true of the various religions throughout the world. But it’s impossible to believe in the one true God and exclude Jesus Christ because He is one of the members of the Trinity. Furthermore, Jesus claimed that He and the Father are one. Another reason people don’t want to acknowledge the deity of Christ is because that makes God too personal and themselves accountable. They prefer a god who will agree with them and help them get whatever they want in life, not one who meddles in their business and holds them responsible. But that is not who the true God is.
Why did Jesus say He came into the world?
He came that we might have life and have it abundantly (John 10:10). The Father sent Him to earth to walk in human flesh, face temptation without sin, and perform miracles that testified of His deity. Eventually He died on a cross to bear the punishment for our sins so that everyone who believes in Him could be forgiven and receive eternal life. And all of this was motivated by God’s love for us (John 3:16). Jesus is the only one who can save us from eternal condemnation.
