Whenever I come together with the brethren, all things are to be done for edification. 1Cor 14.26
I speak in a tongue and edify myself. 1Cor 14.4
I prophesy and edify the church. 1Cor 14.4
Since I am zealous for spiritual gifts, it is for the edification of the church that I seek to excel. 1Cor 14.12
I speak only such a word as is good for necessary edification, that it may impart grace to the hearers. Eph 4.29
