"It is the Will of God that "all sorts of men should be saved and come to an accurate knowledge of truth." (From 1 Tim 2:4 NWT).

HOW WE COME TO KNOW THE TRUTH.
Christ said: "I am the way and the truth and the life. No one comes to the Father except through me." (John 14:6 NWT).

"If you remain in my word, you are really my disciples, and you will know the truth, and the truth will set you free." (From John 8:31 NWT).

"He that says: "I have come to know him," and yet is not observing his commandments, is a liar, and the truth is not in this person. But whoever does observe his word, truthfully in this person the love of God has been made perfect. By this we have the knowledge that we are in union with him." (1 John 2:4,5 NWT).

"If you love me you will obey my commands; and I will ask the Father, and He will give you another to be your Advocate, who will be with you for ever -- the Spirit of truth. The world cannot receive him, because the world neither sees nor knows him; but you know him, because he dwells with you and is in you." (John 14:15-17 NEB).

"True worshippers will worship the Father with spirit and truth, for, indeed, the Father is looking for suchlike ones to worship Him. God is a Spirit, and those worshipping Him must worship with spirit and truth." (From John 4:23,24 NWT).

"Throw off falsehood; speak the truth to each other, for all of us are the parts of one body." (Eph 4:25 NEB).
