Fragment: No Strength but in Christ

There is no strength but in Christ. I have none at any time except as my soul is in secret communion with Him.... Now the direct power of Satan is towards this point, to keep our souls from living on Christ.
One great thing we have to seek is that communion with Christ be as strong as all the doctrines we hold or teach. Without that the doctrine itself will have no force: besides, we ourselves shall not be with God in it, and, after all, that is all.
