Read "I am the Way, Truth, Life" by A. W. Pink
"Pilate therefore said unto him, Art thou a king then? Jesus answered, Thou sayest that I am a king. To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice. Pilate saith unto him, What is truth?" John 18:37-38
What is Truth?
"What is Truth?" asked Pilate. Men have asked this question from generation to generation without hope of an answer, "Ever learning, and never able to come to the knowledge of the truth." 2 Timothy 3:7
Jesus Christ is the truth, but men do not except Him as truth, and therefore continue in darkness. "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me." John 14:6.
The Truth comes to a man only through the Holy Spirit, no man can of himself find it out. "And it is the Spirit that beareth witness, because the Spirit is truth." 1 John 5:6. "And when he, the Spirit of truth, is come, he will guide you into all truth:" John 16:13.
Truth must be sought after, "Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened." Matthew 7:7-8
Truth can be attained, "If ye continue in my word, then are ye my disciples indeed; And ye shall know the truth, and the truth shall make you free." John 8:31-32.
Truth is a hard way to follow, therefore few men go on to perfection. "Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it." Matthew 7:13-14
Truth is infinite, it is deeper than you know. "O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out! For who hath known the mind of the Lord? or who hath been his counseller? Or who hath first given to him, and it shall be recompensed unto him again? For of him, and through him, and to him, are all things: to whom be glory for ever. Amen." Romans 11:33-36
A warning for those who would reject truth, "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; Who changed the truth of God into a lie..." Romans 1:18,25. "That they all might be damned who believed not the truth..." 2 Thessalonians 2:12. "...men of corrupt minds, and destitute of the truth..." 1 Timothy 6:5.
