Why Biblical Preaching

1 Corinthians 14:1-6 NASB
1 Pursue love, yet desire earnestly spiritual gifts, but especially that you may prophesy. 2 For one who speaks in a tongue does not speak to men but to God; for no one understands, but in his spirit he speaks mysteries. 3 But one who prophesies speaks to men for edification and exhortation and consolation. 4 One who speaks in a tongue edifies himself; but one who prophesies edifies the church. 5 Now I wish that you all spoke in tongues, but even more that you would prophesy; and greater is one who prophesies than one who speaks in tongues, unless he interprets, so that the church may receive edifying.

6 But now, brethren, if I come to you speaking in tongues, what will I profit you unless I speak to you either by way of revelation or of knowledge or of prophecy or of teaching?
