That is the condition as suggested by one of our texts--'a man full of faith,' and therefore 'of the Holy Ghost.' Now, of course, I believe, as I suppose all people who have made any experience of their own hearts must believe, that before a soul exercises confidence in Jesus Christ, and passes into the household of faith, there have been playing upon it the influences of that divine Comforter whose first mission is to 'convince the world of sin.' But between such operations as these, which I believe are universally diffused, wheresoever the Word of God and the message of salvation are proclaimed--between such operations as these, and those to which I now refer, whereby the divine Spirit not only operates upon, but dwells in, a man's heart, and not only brings conviction to the world of sin, there is a wide gulf fixed; and for all the hallowing, sanctifying, illuminating and strength-giving operations of that divine Spirit, the pre-requisite condition is our trust. Jesus Christ taught us so, in more than one utterance, and His Apostle, in commenting on one of the most remarkable of His sayings on this subject, says, 'This spake He concerning the Holy Spirit which _they that believed_ in Him were to receive.' Faith is the condition of receiving that divine influence. But what kind of faith? Well, let us put away theological words. If you do not believe that there is any such influence to be got, you will not get it. If you do not want it, you will not get it. If you do not expect it, you will not get it. If professing to believe it, and to wish it, and to look for it, you are behaving yourself in such a way as to show that you do not really desire it, you will never get it. It is all very well to talk about faith as the condition of receiving that divine Spirit. Do not let us lose ourselves in the word, but try to translate the somewhat threadbare expression, which by reason of its familiarity produces little effect upon some of us, and to turn it into non-theological English. It just comes to this,--if we are simply trusting ourselves to Jesus Christ our Lord, and if in that trust we do believe in the possibility of even _our_ being filled with the divine Spirit, and if that possibility lights up a leaping flame of desire in our hearts which aspires towards the possession of such a gift, and if belief that our reception of that gift is possible because we trust ourselves to Jesus Christ, and longing that we may receive it, combine to produce the confident expectation that we shall, and if all of these combine to produce conduct which neither quenches nor grieves that divine Guest, then, and only then, shall we indeed be filled with the Spirit.
