We love God...or at least we try to. CS Lewis noted, "God's love for us is a much safer subject to think about than our love for Him." If we're honest with ourselves, we'll have to admit we usually love a lot of other stuff more than God. We may be faithful to church, but do we have a passion for God?
Jonathan Edwards pointed out: "As there is no true religion where there is nothing else but affection, so there is no true religion where there is no religious affection." It's possible to have zeal yet lack true faith that transforms one's outlook and lifestyle.
Are we inclined toward God? Do we delight in God's glory and majesty? The affection we have for God now is a foretaste of our heavenly happiness.
