Revival means the work of God restoring to a moribund church, in a manner out of the ordinary, those standards of Christian life and experience which the New Testament sets forth as being entirely ordinary; and a right-minded concern for revival will express itself, not in a hankering after tongues (ultimately it is of no importance whether we speak in tongues or not), but rather in a longing that the Spirit may shed God’s love abroad in our hearts with greater power. For it is with this (to which deep exercise of soul about sin is often preliminary) that personal revival begins, and by this that revival in the church, once begun, is sustained.
