The Philistines were afraid, for they said, God is come into the camp. They said, Woe to us! for there has not been such a thing heretofore.
The first lesson is that which I have been insisting upon all through: the necessity of the divine presence. Dear friends, you acknowledge this. There is not one among us who does not know that the Holy Ghost is needful to effect any work. But I am afraid that it is something which we know so well, that we have put it up on a shelf, and there it lies unheeded. But it must not be so with thee, my brother, nor with me. We must pray in the Holy Ghost, or else we shall not pray at all; and we must preach under the influence of the Holy Ghost, or else we shall chatter like sparrows on the window-sill in the morning, and nothing will come of the chattering. Only the Holy Ghost can make anything we do to be effectual. Therefore never begin any work without the Holy Ghost, and do not dare go on with the impetus that you have gained, but cry again for the Holy Spirit. The "amen" of the sermon needs to be spoken in the power of the Holy Ghost just as much as the first word of the discourse, and every word between the first and the last. Let all your service for God be in the Spirit, or else it is all good for nothing.
