Godly Edification is God's Way unto Godly Sanctification
Godly Edification is done by faith-1 Tim 1:4; it is not done by works. At the core of being godly edified is to know, understand, appreciate, and apply a beleiver's New Identity in Christ to their faith and practical living. This New Identity is the only way that the Heavenly Father knows and functions with His sons during the present Dispensation of the Grace of God.
To be godly edified is to be built up in Christ via the sound grace doctrines contained in Paul's 13 epistles. Paul teaches that at the moment when a sinner trusts in Christ [Christ died for all their sins], that the trusting person is spiritually/soulishly taken out of Adam with his marks of identification and is placed into this New Identification found in Christ. God now sees us identified in Christ.
