Jesus Christ, the single most influential man ever, taught that "No man can come to me, except the Father which hath sent me draw him: ..." (John 6:44)
That is the problem. Our Father gives, by His Holy Spirit, some people the ability to hear and to see what is irrefutable Truth. These people who are drawn are the same who hate and repent of evil. If anyone doesn't want to repent of all evil, they can stay hidden in the darkness until death comes upon them, and then they will know that they loved the darkness because their deeds were evil. The love of the Father is therefor not in them. (John 3:19)
I have already given the proofs that I have experienced and witnessed. These weren't good enough and will never be good enough, because they are being disbelieved, ignored, or otherwise simply forgotten about, because that's how the "darkness" operates. I could feed five thousand men, not counting their women and children, with a few loaves of bread and a couple of fish, and afterwards gather up 12 bushel baskets full of food fragments after all those thousands of people ate their fill, and you could be there and the truth would still elude you, somehow, just like it did the disciples of Jesus, who had been there to see Jesus' miracle of the loaves and fish, yet still did not know that He had all the power of God and was going to raise Himself from the dead after being crucified, just as He foretold He would do.
The disciples of Jesus couldn't fully know Him until they had received the power of the Holy Spirit, after His Resurrection and Ascension. Then they knew full well Who Jesus Christ is.
