This word starts by skillfully unveiling or unlocking the riches of Christ; the truths that fashioned Jesus to become the Christ, and ultimately the Son of God (Jn. 20:31).
By receiving and faithfully keeping the riches of Christ it communicates, we are prepared, empowered and equipped with the spiritual maturity and ability to receive the weightier things (teaching) of God; things that border on the fullness of our soul's salvation (Rom. 1:16, 1Cor. 2:9-11).
So, only by the consistent skillful teaching of this word or of the doctrine Christ, can believers who have only been able to carnally relate with the natural life (i.e. with his natural mind or senses) be brought to a place where they can do so gracefully or spiritually; with a mind strictly inspired by Christ; a spiritual mind that pleases God and displeases the devil (Rom. 8:6).
