And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight. Whatsoever we ask - In such a spirit, we receive of him, for he delights to bless the humble, upright, and sincere soul.
Because we keep his commandments - Viz., by loving him and loving our neighbor. These are the great commandments both of the old covenant and the new. And whoever is filled with this love to God and man will do those things which are pleasing to him; for love is the very soul and principle of obedience.
