“And to know the love of Christ, which passeth knowledge, that ye might be filled with all the fulness of God.”Ephesians 3:19.
(AG 312.1)
God calls upon those who know His will to be doers of His word. Weakness, halfheartedness, and indecision provoke the assaults of Satan; and those who permit these traits to grow will be borne helplessly down by the surging waves of temptation....
(AG 312.2)
Every means of grace should be diligently improved that the love of God may abound in the soul more and more, “that ye may approve things that are excellent; that ye may be sincere and without offense till the day of Christ; being filled with the fruits of righteousness” (Philippians 1:10, 11). Your Christian life must take on vigorous and stalwart forms. You can attain to the high standard set before you in the Scriptures, and you must if you would be children of God. You cannot stand still; you must either advance or retrograde. You must have spiritual knowledge, that you “may be able to comprehend with all saints what is the breadth, and length, and depth, and height; and to know the love of Christ,” that you may “be filled with all the fulness of God”(Ephesians 3:18, 19) ....
(AG 312.3)
Will you have a stinted Christian growth, or will you make healthy progress in the divine life? Where there is spiritual health there is growth. The child of God grows up to the full stature of a man or woman in Christ. There is no limit to his improvement....
(AG 312.4)
We have great victories to gain, and a heaven to lose if we do not gain them. The carnal heart must be crucified; for its tendency is to moral corruption, and the end thereof is death. Nothing but the life-giving influences of the gospel can help the soul. Pray that the mighty energies of the Holy Spirit, with all their quickening, recuperative, and transforming power, may fall like an electric shock on the palsy-stricken soul, causing every nerve to thrill with new life, restoring the whole man from his dead, earthly, sensual state to spiritual soundness. You will thus become partakers of the divine nature, having escaped the corruption that is in the world through lust; and in your souls will be reflected the image of Him by whose stripes you are healed.—Testimonies for the Church 5:263-267.
