I don’t have to pray about that!
Have you ever heard someone explain that they didn’t need to ask God about a particular situation? Perhaps you’ve been that person—so confident that you already know God’s will that you don’t need to confirm it? There seems to be an agreement in the church that some things are so obvious, we don’t need to check in with God about them.
I suppose you could make a case for instances where God’s will is clearly stated in the Bible. We probably don’t need to ask Him whether or not we should murder that annoying neighbor, for example. Nor do we need to pray about if we should cheat on our spouse.
