The Holy Spirit is the only one who can kill us and keep us dead. Many Christians try to do this disagreeable work themselves, and they are going through a continual crucifixion, but they can never accomplish the work permanently. This is the work of the Holy Spirit, and when you really yield yourself to the death, it is delightful to find how sweetly He can slay you.
By the touch of the electric spark they tell us life is extinguished almost without a quiver of pain. But, however this may be in natural things, we know the Holy Spirit can touch with celestial fire the surrendered thing, and slay it in a moment, after it is really yielded up to the sentence of death. That is our business, and it is God's business to execute that sentence, and to keep it constantly operative.
Don't let us live in the pain of perpetual and ineffectual suicide, but reckoning ourselves dead indeed, let us leave ourselves in the hands of the blessed Holy Spirit, and He will slay whatever rises in opposition to His will, and keep us true to our heavenly reckoning, and filled with His resurrection life.
