IF you are an honest doubter, let me ask you to pray, “O God, if there be a God show me the truth and I will follow it." Read the book of John and walk in the light as fast as he reveals it to you, and if you do not understand everything at once, remember you do not understand many other things you use and believe;
BUT these (the writings of John’s gospel) are written that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through His name.
John 20:31.
IF any man will do his will, he shall know of the doctrine.
John 7:17.
God tells us that an unregenerated man cannot understand spiritual things.
BUT the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
I Corinthians 2:14.
The blind man (Mark 8:24), saw “men as trees.” walking when Christ first gave him sight, but he used what sight he had and then Christ gave him more.
If you use the light you have, the Spirit will give you more. Many have had the same experiences through which Thomas the Apostle, passed; read it.
EXCEPT I shall see in his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe. And after eight days again his disciples were within, and Thomas with them: then came Jesus, the door being shut, and stood in the midst, and said, Peace be unto you. Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My Lord and my God.
John 20:25-28.
