According to God’s Word, everything will be made known. “No one will know” is probably what many people thought when they committed crime or sin.  The knowledge that everything is laid bare and naked eventually… will help the teachable to do what is right.

Luke 12:2 (NIV) There is nothing concealed that will not be disclosed, or hidden that will not be made known. 3 What you have said in the dark will be heard in the daylight, and what you have whispered in the ear in the inner rooms will be proclaimed from the roofs.

1Cor 4:4 (NIV) My conscience is clear, but that does not make me innocent. It is the Lord who judges me. 5 Therefore judge nothing before the appointed time; wait until the Lord comes. He will bring to light what is hidden in darkness and will expose the motives of the heart. At that time each will receive their praise from God.

Hebrews 4:13 (NIV) Nothing in all creation is hidden from God’s sight. Everything is uncovered and laid bare before the eyes of him to whom we must give account.
