I have to account to God for the way in which I rule my body under His domination. Paul said he did not “frustrate the grace of God” — make it of no effect. The grace of God is absolute, the salvation of Jesus is perfect, it is done for ever. I am not being saved, I am saved; salvation is as eternal as God’s throne; the thing for me to do is to work out what God works in. “Work out your own salvation”; I am responsible for doing it. It means that I have to manifest in this body the life of the Lord Jesus, not mystically, but really and emphatically. “I keep under my body, and bring it into subjection.” Every saint can have his body under absolute control for God. God has made us to have government over all the temple of the Holy Spirit, over imaginations and affections. We are responsible for these, and we must never give way to inordinate affections. Most of us are much sterner with others than we are in regard to ourselves; we make excuses for things in ourselves whilst we condemn in others things to which we are not naturally inclined.

“I beseech you,” says Paul, “present your bodies a living sacrifice.” The point to decide is this — “Do I agree with my Lord and Master that my body shall be His temple?” If so, then for me the whole of the law for the body is summed up in this revelation, that my body is the temple of the Holy Ghost.
