Sin will find you out

David probably thought his sin with Bathsheba was hidden forever, but generation upon generation has knowledge of his murderous affair.

Judas probably thought that no one would know it was he who betrayed Christ, but it is recorded in holy writ for all eternity.

Scripture says:
Therefore, whatever you have said in the dark will be heard in the light, and what you have whispered in an ear in private rooms will be proclaimed on the housetops. Luke 12:3 HCSB

and

"I, the LORD, search the heart, I test the mind, Even to give to each man according to his ways, According to the results of his deeds. Jeremiah 17:10 NASB

We have a holy walk before the Lord because of our love for Him and because of His commandments.

For this is the love of God, that we keep his commandments: and his commandments are not grievous.
(1 John 5:3 KJV)

And, if this love fails you for a brief moment Christian, have a holy walk for fear of the Lord because he searches our hearts and your sin will find you out.
