We do not need to know every subtle bend in the road to avoid evil. We have clear commands given in the word. If we follow those obvious commands the subtle variations and blind spots will be covered. Remember when Jesus was talking to the sheep and the goats in Matthew 25. Both of them asked the same question.
(Matthew 25:44 KJV) Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee?Both were prepared to take care of Jesus because that was the obvious move to make. Only the righteous sheep obeyed when they didn’t think Jesus was watching.
