'God is Great' in the Bible

I say unto you, among those having been born of women no prophet is greater than John the Baptist; nevertheless the least in the kingdom of God is greater than he.

because if our heart may condemn us, it is because God is greater than our heart, and he knows all things.

If we receive the witness of men, the witness of God is greater: because this is the witness of God that he has testified concerning his Son.
