(Proverbs 4:19 KJV) The way of the wicked is as darkness: they know not at what they stumble.
Evil in our hearts removes our understanding of cause and effect because we refuse to see. It is like walking through the house at night in the dark and finding that someone has moved all the furniture. You did not give them permission. They didn’t ask. You have that hassock that is the perfect height for putting your feet on. In the dark it is also the perfect height to break your toe. In the dark any height will do. What could be useful and of great value trips us instead of blessing us. That is what evil does. It causes us to “stumble” (3782) over the good as well as the bad. It removes discernment.
How often have I tripped over something in the dark and I don’t know what it was? There should have been nothing in that spot. I still tripped. My ignorance does not remove the pain in my toe.
So? Have you turned on the light today? Have you taken the light of the word and directed it toward those areas that you are not sure about? It is amazing how a small flashlight can help you see which wire is the ground and which can kill you.
