God will fill the hungry because He Himself has stirred up the hunger. As in the case of prayer, when God prepares the heart to pray, He prepares His ear to hear (Ps. 10:17). So in the case of spiritual hunger, when God prepares the heart to hunger, He will prepare His hand to fill.
Thomas WatsonMake up your spiritual accounts daily; see how matters stand between God and your souls (Psalm 77:6). Often reckonings keep God and conscience friends. Do with your hearts as you do with your watches, wind them up every morning by prayer, and at night examine whether your hearts have gone true all that day, whether the wheels of your affections have moved swiftly toward heaven.
Thomas Watson
