1 Corinthians 2:14
The natural man receiveth not the things of the spirit of God: for they are foolishness unto him.
It has pleased God to say many things which leave room for misunderstanding, and not to explain them. Often in the Bible there seem to be conflicting statements, or statements that seem to violate the known facts of life, and it has pleased Him to leave them there.
There are many scriptures we cannot clearly explain. Had we been writing we would have put things far more plainly, so that men should have before them all the doctrine in foolproof systematic order. But would they have had the life?
The mighty eternal truths of God are half obscured in Scripture so that the natural man may not lay hold of them. God has hidden them from the wise to reveal them to babes, for they are spiritually discerned.
His Word is not a study book. It is intended to meet us in the course of our day-to-day walk in the Spirit and to speak to us there.
It is designed to give us knowledge that is experimental because related to life. If we are trying through systematic theology to know God, we are absolutely on the wrong road.
