Apparently God has developed a mental barrier in His children to discern right and wrong (the law of conscience). But in some occasions God may decide to retract His staying power over our mental abilities in a way our mental capabilities become hindered and those who commit these types of evils (unthankfulness, unbelief, vain, entitlement -Romans 1:21), those who commit those types of evils find their culmination and fulfillment only in more despair (Romans 1:22). Hurt and potentially a depression or insanity (-Romans 1:24,26,28). There is part of a poem that I wish to share at this point that really helps describe what is happening here to the saved soul that makes it depart from living faith. There is a time, we know not when,A point we know not where, That marks the destiny of men To glory or despair. There is a line by us unseen,That crosses every path; The hidden boundary between God’s patience and his wrath. To pass that limit is to die–To die as if by stealth; It does not quench the beaming eye Or pale the glow of health. The conscience may be still at ease,The spirit lithe and gay; That which pleases still may please, And care be thrust away But on that forehead God has set,Indelibly a mark Unseen by men, for men as yet Are blind and in the dark And yet doomed man’s path belowMay bloom as Eden bloomed; He did not, does not, will not know, Or feel that he is doomed He knows, he feels that all is well,And every fear is calmed; He lives, he dies, he wakes in hell, Not only doomed, but damned. Oh, where is this mysterious bournBy which our path is crossed; Beyond which God himself hath sworn, That he who goes is lost. a partial poem by Joseph Addison Alexander (1809-1860), called "The Hidden line" this salvation that cannot be lost but forfeited, and left is talked about in Hebrews 6, where we see just as Jesus a few verses earlier tasted death for all men (Heb 2:9), we see that some will taste of life, and yet still die (Hebews 6:4-6) Yes we are saved by faith alone, but some times we can sin one too many times, in a way that that unrepentant sin will decieve us as into not believing in Christ any more. God may at that point harden your heart, and there will be no more option for repentance after that. But with God all things is possible. And God can cause us to turn around, but again He won't give you salvation if you really want hell. It's a very sobering message, the difference between the wicked and the saved is one thing. Repentance. We are now something that we were not before. And we are thankful for that.
