that you keep the commandment without spot, blameless, until the appearing of our Lord Jesus Christ;
So Jesus when He comes is going to show who the true, the only God is. "The only and blessed Potentate, the King of kings, and the Lord of lords; who only hath immortality, who dwells in a light which no man can approach; whom no man hath seen." In John, the first chapter, we read, "No man hath seen God at any time; but the only begotten Son, who is in the bosom of the Father, he has manifested him" ( John 1:18 ). But Jesus will show us then who is the only true God.
