If we reject the truth when we hear it there’s nothing left but fallacy and fable
“Then said Jesus to those Jews which believed on him, 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 KJV
“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.”
John 18:37
“Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me. He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him. Jesus answered and said unto him, If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him. He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me.”
John 14:6, 21, 23-24 KJV
If we find a reason to reject his word of life in the gospel there’s nothing left to accept but false doctrine or lies about the world without a god ……
“and with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
And for this cause God shall send them strong delusion, that they should believe a lie: that they all might be damned who believed not the truth, but had pleasure in unrighteousness.”
2 Thessalonians 2:10-12 KJV
Everyone needs to hear the truth and choose there just the one truth ordained of God , Jesus Christ and the gospel
