Heart and Soul.
With my whole heart and soul. With all the energy and enthusiasm of which I am capable. In French, “S’y porter de tout son cœur.” Mark xii. 33 says, “Love [God] with all thy heart [affection], all thy soul [or glow of spiritual life], all thy strength [or physical powers], and all thy under-standing [that is, let thy love be also a reasonable service, and not mere enthusiasm].”
