The Bible mentions the existence of an unforgivable sin, and this has greatly frightened innumerable Christians.
Let us be absolutely clear upon one point. There is no sin that a human being can commit that God will not forgive but there is one sin that he cannot forgive until we make it possible. This sin consists in shutting ourselves off from fresh inspiration or guidance from God. If your mind is already made up about everything appertaining to God; if you decide that you now know all the truth, and that you could not be mistaken; then it will not be possible for the Holy Ghost to open your eyes to error and lead you into higher truth. Naturally, as long as this is your state of mind, no help or improvement can come to you; and in that sense only is your sin unforgivable – unforgivable while it lasts. When you do change your attitude, enlightenment will come, and the sin will be destroyed.
Behold, I stand at the door, and knock; if any man hear my voice, and open the door, I will come in to him, and will sup with him and he with me (Revelation 3:20).
The most common way of shutting off God’s ongoing revelation is to deny that we have acted wrongly and our inability thereby to seek forgiveness. This is not the same as being ignorant that our actions are wrong. Willful actions that violate our spiritual values, yet are denied by us as wrongdoing can not be forgiven. The reason why is simple. God can not forgive us until we admit we have done something wrong?
A child raised in a culture that celebrates wrong behavior may not know that such activity is wrong. God can forgive them just as he can answer the prayers that we do not know enough to pray ourselves. God can and will give us that which we need even when we don’t know what that is.
However, neither will God forgive, nor can he forgive, willfully wrong behavior that we justify because of circumstances. “He hurt me”, or “She needed to be taught a lesson”, are rationalizations that do not justify our violation of spiritual laws. And until we admit their wrongness, repent of the wrong and ask forgiveness, God can not and would not forgive us for it.
The good news is all we have to do is face the truth, accept responsibly and ask forgiveness. Then we open the door and God will come in and sup in our gardens with us. And all will be well.

Reminds me of Job proclaiming his self-righteousness to his own hurt. When, finally, his eyes are opened and he truly repents, his fortunes are reversed to the point of having twice as much as he did in his former good life.
Something about being self-honest and willing to repent!
Sometimes the hardest thing to see is ourselves!
A response from a friend.
Beautifully and effectively said.
This one, reflecting millennia of spiritual thought, is still most difficult to get right. It requires openness and faith in circumstances, good or bad, that mitigate against opening one’s self. Problem is, when we are the problem, we can’t see the problem.
Thanks for this one.
Always good to recall that there’s a ready and willing God.
