Truth is what God thinks; it is what God does; it is what God is; it is what God has revealed of Himself in the Bible.

Truth is what God thinks; it is what God does; it is what God is; it is what God has revealed of Himself in the Bible. Truth is found in its fullest form in God, for He is truth; He is the very source and origin of all truth.
