Have you ever noticed that most robberies take place when it is dark? Jesus says that He sees even in the dark. There are people who wait until their family has gone to bed, and then they get on the computer and go to adult websites. Jesus sees them also.
Not only does Jesus see what actions we do in the dark, He also sees the dark thoughts of our heart and mind. He sees all the bitterness, unforgiveness, and hatred.
You may think that no one sees when you are beating your spouse and children, but Jesus sees you. It is impossible to hide from Jesus. If we ever get a grasp on this concept, I think our attitudes and habits will change for the better.
What does Jesus see when He looks into your heart? Is your heart filled with the things that bring Joy to Him, or is it filled with things that bring shame to Him and break His Heart?
