Sin is committed by many who think their crime is effectually concealed. But there is One who says, “I know thy works” ; “there is nothing covered which shall not be revealed; and hid, which shall not be known.” Luke 12:2. When the mind is infatuated with the idea of sin, there will be deception practiced; lies will be told; for those who commit such sins will not be slow to lie as well. But all sin shall be revealed. (TSB 88.4) MC VC

I dare not keep these things from you. I hope you will now seek the Lord with your whole heart, that you may find Him. Better go in humility all the rest of your life than to lose your own soul and be the means of other souls being lost through your course of action. Sin does not appear exceeding sinful to you, but God says, “I know thy works.” So every deception you have practiced, every false word you have uttered, and to every unholy action there has been a watcher from whom you could not exclude yourself. (TSB 139.2) MC VC
