“The Heart Is the Organ of Worship Because the heart is so active with its passions, affections, and desires, it is the organ with which we worship. Deuteronomy 11:16 warns, “Take care lest your heart be deceived, and you turn aside and serve other gods and worship them.” Jesus says, “This people honors me with their lips, but their heart is far from me; in vain do they worship me, teaching as doctrines the commandments of men” (Matt. 15:8–9).” (location 1307 Kindle edition)
