1 Corinthians 2:14
But the natural man receives not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
1 Corinthians 9:11
If we have sown unto you spiritual things, is it a great thing if we shall reap your material things?
1 Corinthians 10:3
And did all eat the same spiritual food;
Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord;
Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.
