We often pray for forgiveness, and in one such prayer we should ask God to forgive us for those things we have left undone. Have you ever prayed this way and wondered what those undone things and sins might be? Well, the most powerful example of these is not witnessing in word or deed to a sinner, either unsaved, or who has wandered away from their faith. Not witnessing when we are able places the blood of that soul upon us, but by obedience we save our own souls.
