'Edification' in the Bible

So then, let us pursue [with enthusiasm] the things which make for peace and the building up of one another [things which lead to spiritual growth].

Let every one of us please his neighbour for his good to edification.

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

and I wish you all to speak with tongues, and more that ye may prophecy, for greater is he who is prophesying than he who is speaking with tongues, except one may interpret, that the assembly may receive edification.

Thus ye also, since ye are desirous of spirits, seek that ye may abound for the edification of the assembly.

What then is the conclusion, brothers? Whenever you come together, each one has a psalm, a teaching, a revelation, another language, or an interpretation. All things must be done for edification.

For though I should boast somewhat more of our authority, which the Lord hath given us for edification, and not for your destruction, I should not be ashamed:

Have you been thinking all this time that we are defending ourselves to you? We are speaking in Christ before God, and all [these things], dear friends, [are] for your edification.

Therefore I write these things being absent, lest being present I should use sharpness, according to the power which the Lord hath given me to edification, and not to destruction.

Let no corrupt word go out of your mouth, but if there be any good one for needful edification, that it may give grace to those that hear it.
