He that is true is evidently the true One, or true God. This is life eternal, that they might know Thee, the only true God, to give us a mind capable of knowing and comprehending this true God. It is not a God that we need to know, but the God, the one living and true God. There is no knowledge of God out of Christ, apart from Christ, or without Christ. Where the knowledge of Christ is not, there is utter ignorance of God, the worship of a false or unknown god.
False worship is a serious thing, a fearful sin, a hideous blasphemy.
Falsehood touching God is infinite dishonor. It is the true God that is to be worshipped, none else. He will not give His glory to another. Nor will the knowledge of any false god fill or pacify the soul. It is only that God whom Jesus of Nazareth revealed that will suffice for the human spirit.
