“But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised. But he who is spiritual appraises all things, yet he himself is appraised by no one. For who has known the mind of the Lord, that he will instruct Him? But we have the mind of Christ.” 1Corinthians 2:14-16
Beware of one facet of the carnal nature in you Scripture calls, “the natural man.” The natural man wants to believe and obey only what he understands completely. He won’t do anything until he knows that he won’t look stupid or foolish in front of others, therefore our natural man is incapable of living by faith and cannot please God. (See Hebrews 11:6; Romans 8:8)
It is easy to be born of the Spirit at some point in the past, but not walk in the Spirit today. When that happens we are miserable as Christians, kind of like fish out of water. Our proper habitat is the spirit realm, so when we go back to living like those in the world we become spiritually choked.
Signs of a Christian living in the natural man include anxiety, joylessness, cynicism, discouragement, and feeling spiritually drained all the time. The answer is not complicated; put off the old man and walk in the Spirit. (Ephesians 4:22-23; Galatians 5:25) Start by asking God to forgive you for trying to live the Christian life by the natural man, then remember that your rightful breath is the Holy Spirit, your proper food is the Word of God, and your sure hope for eternity is heaven no matter what happens down here. You have only God to please, so it doesn’t matter whether others approve of you or not.
The language of the Spirit does not contradict our minds, but it does transcend it. His many ways of whispering to us must be spiritually appraised, so we must stay alert to the spirit realm. God is in charge of planning, protecting, providing, and guiding. We are in charge of trusting and obeying. It’s a nice arrangement when we do our part and don’t question His!
