In all these passages, edification has two meanings. Collectively it refers to the building up of the body of Christ. For individual believers, edification refers to the spiritual growth and momentum in the Christian way of life, resulting in the glorification of God. To grow in Christ, a Christian must be consistent on a daily basis in staying in fellowship with the Lord through confession of sin, and learning and applying Bible teaching.
Edification is the means of advancement and productivity in the Christian way of life.
Doctrine that is learned must feed both the human spirit and the human soul for capacity for both human and eternal life. Edification of the soul is the result. The growth of Christian love is a sign that a person has been learning and applying doctrine. Personal love for God the Father is and motivation for the reception of doctrine. Impersonal love for all mankind is functional love.
