To hearken is “to attend; to regard; to give heed to what is uttered; to observe or obey” (Webster, American Dictionary).
“Above all, God’s children should learn to listen, then listen to learn from the Lord. … Scriptures recorded in all dispensations teach that we show our love of God as we hearken to His commandments and obey them. These actions are closely connected. In fact, the Hebrew language of the Old Testament in most instances uses the same term for both hearkening (to the Lord) and obedience (to His word)” (Nelson, “Listen to Learn,” 24). What does it show the Lord when we hearken to Him?
