Paul, a servant of God and an apostle of Jesus Christ, for the sake of the faith of God’s elect and their knowledge of the truth, which accords with godliness, in hope of eternal life, which God, who never lies, promised before the ages began —Titus 1:1-2 ESV
Admit the very possibility of His speaking an untruth and to the Christian there would be no God at all. The depraved mind of the heathen may imagine a monster to be a god who can live in adultery and in theft and in lying, for such the gods of the Hindus are described as being. But the enlightened mind of the Christian can conceive no such thing. The very word “God” comprehends everything which is good and great. Admit the lie and to us at once there would be nothing but the black darkness of Atheism. I could neither love, worship, nor obey a lying God.
