'The God of hope fill you ...'--let us leave out the intervening words for a moment--'in believing.' Now, you notice that Paul does not stay to tell us what or whom we are to believe in, or on. He takes that for granted, and his thought is fastened, for the moment, not on the object but on the act of faith. And he wishes to drive home to us this, that the attitude of trust is the necessary prerequisite condition of God's being able to fill a man's soul, and that God's being able to fill a man's soul is the necessary consequence of a man's trust. Ah, brethren, we cannot altogether shut God out from our spirits. There are loving and gracious gifts that, as our Lord tells us, He makes to 'fall on the unthankful and the evil.' His rain is not like the summer showers that we sometimes see, that fall in one spot and leave another dry; nor like the destructive thunderstorms, that come down bringing ruin upon one cane-brake and leave the plants in the next standing upright. But the best, the highest, the truly divine gifts which He is yearning to give to us all, cannot be given except there be consent, trust, and desire for them. You can shut your hearts or you can open them. And just as the wind will sigh round some hermetically closed chamber in vain search for a cranny, and the man within may be asphyxiated though the atmosphere is surging up its waves all round his closed domicile, so by lack of our faith, which is at once trust, consent, and desire, we shut out the gift with which God would fain fill our spirits. You can take a porous pottery vessel, wrap it up in waxcloth, pitch it all over, and then drop it into mid-Atlantic, and not a drop will find its way in. And that is what we can do with ourselves, so that although in Him 'we live and move and have our being,' and are like the earthen vessel in the ocean, no drop of the blessed moisture will ever find its way into the heart. There must be man's faith before there can be God's filling.
