Hebrews 5:11~14
11. We have much to say about this, but it is hard to explain because you are slow to learn.
12. In fact, though by this time you ought to be teachers, you need someone to teach you the elementary truths of God's word all over again. You need milk, not solid food!
13. Anyone who lives on milk, being still an infant, is not acquainted with the teaching about righteousness.
14. But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil.
1 Corinthians 2:10~16
10. but God has revealed it to us by his Spirit. The Spirit searches all things, even the deep things of God.
11. For who among men knows the thoughts of a man except the man's spirit within him? In the same way no one knows the thoughts of God except the Spirit of God.
12. We have not received the spirit of the world but the Spirit who is from God, that we may understand what God has freely given us.
13. This is what we speak, not in words taught us by human wisdom but in words taught by the Spirit, expressing spiritual truths in spiritual words.
14. The man without the Spirit does not accept the things that come from the Spirit of God, for they are foolishness to him, and he cannot understand them, because they are spiritually discerned.
15. The spiritual man makes judgments about all things, but he himself is not subject to any man's judgment:
16. "For who has known the mind of the Lord that he may instruct him?" But we have the mind of Christ.
