Once and a while, even Berkhof has some great things to say ; )
“They who are united to Christ by faith become partakers of His Spirit, and thus become one body with Him, pulsating with the life of the Spirit. They share in the life of Christ, and because He live they live also. It is impossible that they should again be removed from the body, thus frustrating the divine ideal. The union is permanent, since it originates in a permanent and unchangeable cause, the free and eternal love of God.”
He goes on to quote Dabney on the work of the Spirit, of which I like particularly the following phraseology,
“It is a low and unworthy estimate of the wisdom of the Holy Spirit and of His work in the heart to suppose that He will begin the work now, and presently desert it; that the vital spark of heavenly birth is an ignis fatuus, burning for a short season, and then expiring in utter darkness; that the spiritual life communicated in the new birth, is a sort of spasmodic or galvanic vitality, giving the outward appearance of life in the dead soul, and then dying.”
