Literally “building up,” it approximates encouragement and consolation (1 Cor 14:3; 1 Thess 5:11); though with edification focus falls on the goal, defined as being established in faith (Col 2:7) or attaining unity of faith and knowledge, maturity, and the full measure of Christ (Eph 4:13). Edification is the special responsibility of the various church leaders (Eph 4:11-12) and is the legitimate context for the exercise of their authority (2 Cor 10:8; 13:10). The work of building up is, however, the work of all Christians (1 Thess 5:11), Spiritual gifts are given for the edification of the church. Of these gifts, those that involve speaking are especially important (1 Cor 14; Eph 4:29). All elements of Christian worship should contribute to edification (1 Cor 14:26). Prophecy and instruction are especially important (1 Cor 14:3, 18-19). Edification is not all talk, however, but involves demonstrating love (1 Cor 8:1) and consideration for those weak in faith (Rom 15:1-2).
1 CORINTHIANS 14:3 – 3 But he that prophesieth speaketh unto men to edification, and exhortation, and comfort.
1 THESSALONIANS 5:11 – 11. Wherefore comfort yourselves together, and edify one another, even as also ye do.
EPHESIANS 4:13 – 13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:
EPHESIANS 4:29 – 29 Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.
ROMANS 15:1-2 – 1. We then that are strong ought to bear the infirmities of the weak, and not to please ourselves.
2 Let every one of us please his neighbour for his good to edification.
