“Do not be deceived-- one sin will send you to hell as fast as a thousand. "1Cor. 6:9 (AMP) Do you not know that the unrighteous and the wrongdoers will not inherit or have any share in the kingdom of God? Do not be deceived (misled): neither the impure and immoral, nor idolaters, nor adulterers, nor those who participate in homosexuality, 10 Nor cheats (swindlers and thieves), nor greedy graspers, nor drunkards, nor foulmouthed revilers and slanderers, nor extortioners and robbers will inherit or have any share in the kingdom of God. Scripture excludes not only the man who is all of these, but he who is any of them. All men must die, but they do not die of the same disease. And it is just as certain that all unrepentant sinners will be damned-- one for a particular sin and another for something else. But they will all meet in the same flaming hell.
Satan tempts us with secret sins. Saul was ashamed to approach Endor in his princely robe because he had told the world of his hatred of witchcraft, making it punishable by death. But he was not afraid to go to a witch in disguise. What weight is added, then, to the devil's sinister motive when he tempted Christ in the wilderness, soliciting Him to a secret acknowledgement of him, just between the two of them. But how much greater was Christ's glory in His victory that day! He won the battle over Satan's assaults with the sword of the Word-- and it is time for us to take up His weapon to fight the same enemy. This defense takes on several specific expressions.
Scripture says God knows every secret sin. "Psa. 90:8 (AMP) Our iniquities, our secret heart and its sins [which we would so like to conceal even from ourselves], You have set in the [revealing] light of Your countenance. God sees secret sins as plainly as we see things at high noon. And He not only knows them but sets them up as targets for His arrows of vengeance.
"Prov. 15:3 (AMP) The eyes of the Lord are in every place, keeping watch upon the evil and the good." He sees when you close your closet door to pray in secret and rewards your sincerity; but He also sees when the door is closed for you to sin in secret-- and He will not fail to reward your hypocrisy.”Quoted material from, ”The Christian in Complete Armour Daily Readings in Spiritual Warfare” by Gurnall and James S Bell. http://www.moodypublishers.com/pub_productDetail.aspx?id=41823&pid=53617
