I have been asked by the publishers to write a few lines introducing this book to American Christians. I count it a privilege to be allowed to do so. _The one thing needful_ for the church of Christ in our day, and for every member of it, is to be filled with the spirit of Christ. Christianity is nothing except as it is a ministration of the Spirit. Preaching is nothing, except as it is a demonstration of the Spirit. Holiness is nothing except as it is the fruit of the Spirit. These truths are so little taught or emphasized as they should be, and the blessings they speak of are so little experienced that one gladly welcomes every voice that draws attention to them. It is known that all do not perfectly agree as to the best answer to the question: How to be filled with the Spirit? Some press that aspect of truth which reminds us that the Holy Spirit _has been given_ to the church and that He dwells in every believer, a fountain of living water. As there have been fountains clogged by stones and earth, and only needing to be cleared and opened up, so we have only to remove the hindrances, to yield ourselves in perfect surrender to the Spirit in us, and the filling will come. We must not ask God for more of the Spirit. God asks for more of us that the Spirit may have us wholly. Others, while admitting fully that the Spirit is in the believer, and that He asks for a more entire surrender, yet urge that it is from God direct that the filling of the Spirit must ever still be asked and received. God cannot give His spiritual gifts apart from Himself, once for all. As the divine and everlasting One, He gives unceasingly. The Spirit has not been given as if He had left heaven. He is in God and in the church. It is from God Himself that larger measures of the Spirit must ever be sought and received. Among those who hold this latter view, there is again somewhat of a diversity in the representation of truth. On the one hand we are reminded that it is "_by faith_" we receive the Holy Spirit, and that faith often has to rest and to act without any conscious experience--has to walk in the dark. Souls that are _fully surrendered_ to God are invited to claim the promise and then to go and work in the full assurance that the Spirit is in them, and will in His fullness work through them. On the other hand stress is laid on the words "_we receive_ the Spirit" by faith. The difference between believing and receiving is pointed out, and we are urged to wait until we receive what we claim, and know that God has anew filled us with His Spirit. "To be filled with the Spirit" is offered us as a definite, conscious experience.
