Luke 8:17

‘For nothing is hid, that shall not be made manifest, nor anything secret, that shall not be known and come to light.'

Indeed he reminds us that in the end everything will be revealed, and nothing will finally be hidden. God's light shines on it now for those who have eyes to see. And there is coming a day when God will judge the secrets of men though Christ. Then everyone will have to come to the light. So there is one thing that we can be sure of, and that is that whatever we have done and have tried to cover up must either be brought to the light now (John 3:18) or will one day be openly revealed when all have to give account. Nothing will be hidden. And it will be by the One from Whom nothing can be hidden, and to Whom men have made such all-sweeping promises and commitments. One day all will be brought into the light and each of us will be known for what we really are.

Thus it behoves us as Christians to bring all our sins to the light now so that the blood of Jesus Christ His Son might cleanse us from all sin (1 John 1:7). And then when that day comes we will have nothing to fear, for all our sin will have been dealt with.
