Is Jesus Christ God? Is He The Son Of God?

1 John 5:4-5

For whatever is born of God overcomes the world. And this is the victory that has overcome the world—our faith. Who is he who overcomes the world, but he who believes that Jesus is the Son of God?

Those who deny Jesus Christ as the Son Of God, not only void their chances of knowing God, they also eliminate their chances of having the eternal life that He brings. That life is abundant (John 10:10)
