Jesus called Himself "the Truth" and the Holy Spirit is known as the Spirit of Truth". Because God is entirely trustworthy and true in all He says and does, His word is also described as truth. In keeping with this fact, the Bible makes it plain that God does not tolerate lies or falsehood of any kind.
Numbers 23:19 "God is not a man, that He should lie; neither the son of man, that He should repent: hath He said and shall He not do it? or hath He spoken, and shall He not make it good?"
Heb. 6:18 "That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refute to lay hold upon the hope set before us."
John 14:6 "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me."
John 14: 17 "Even the Spirit of truth; whom the world cannot receive because it seeth Him not, neither knoweth Him: but ye know Him, for He dwelleth with you, and shall be in you."
