of Infinite Importance

"The Great God values not the service of men, if the heart be not in it; The Lord sees and judges the heart; he has no regard to outward forms of worship, if there be no inward adoration, if no devout affection be employed therein. It is therefore a matter of infinite importance, to have the whole heart engaged steadfastly for God." - Isaac Watts

Is having your whole heart engaged steadfastly for God a matter of infinite importance to you?

"Blessed are those who keep his testimonies, who seek him with their whole heart..." - Psalm 119:2
