1 Corinthians 14:3

But he that prophesieth speaketh unto men edification, and exhortation, and consolation.

'But' -in contrast to the tongues. In. congregation where everyone spoke the same language, prophesy, inspired preaching in the common language of the audience was the more useful gift.

'edification, and exhortation, and consolation' -'is speaking to his fellow men words that will build up faith' (TCNT); 'they stimulate and they encourage.' (NEB)

'edification' -3619. oikodome oy-kod-om-ay'; feminine (abstract) of. compound of 3624 and the base of 1430; architecture, i.e. (concretely). structure; figuratively, confirmation: -building, edify(-ication, -ing).

Much of this letter has stressed the need to pursue those things which promote spiritual growth in others. (1 Corinthians 8:1; 1 Corinthians 10:23)

'exhortation' -3874. paraklesis par-ak'-lay-sis; from 3870; imploration, hortation, solace: -comfort, consolation, exhortation, intreaty. 'calling to one's side' (Robertson p. 181) This word can mean encouragement, comfort or exhortation (appeal).

This was the aim of inspired preaching, it is also the goal of "regular" preaching. (2 Timothy 4:2) God wants balanced preaching. Preaching that promotes spiritual growth, that exhorts (including encouragement, rebuke and admonition) and that offers comfort.

The gift of prophecy offered all these things to the people that heard the prophet speak, for the very simple reason that prophets spoke in the common language of the audience they were addressing.
