“God is greater than our heart” (1 John 3:20)
God created man in His own image and likeness. We have emotions and desires because God does. He is a passionate being, not the “Unmoved Mover” of Aristotle. He is deeply affected by the things which happen in the world He made. Such is clear from the opening pages of the Bible: “And GOD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually. And it repented the LORD that he had made man on the earth, and it grieved him at his heart.” (Genesis 6:5,6)
It is also true that God wants us to come before Him with all our emotions and desires. “… I have roared by reason of the disquietness of my heart. Lord, all my desire is before thee; and my groaning is not hid from thee.” (Psalm 38:8,9) God knows us already, but He wants us to be vulnerable before Him. “Trust in him at all times; ye people, pour out your heart before him: God is a refuge for us. Selah.” (Psalm 62:8)
But accepting the reality that we have strong feelings and desires does not mean that they should control us. Despite how powerful they are at times, God gives them no permission to rule us. He remains Lord. Obedience to His commands are still required. The Lord and His voice must be greater than the most turbulent churning of our heart. “The LORD on high is mightier than the noise of many waters, yea, than the mighty waves of the sea.” (Psalm 93:4) “… What manner of man is this, that even the wind and the sea obey him?” (Mark 4:41)
Left unchecked, strong emotions and desires can move us into direct disobedience to God and His Word. They are not to be subject to reason, they are to be subject to the Lordship of Jesus Christ. The wind and the sea once obeyed Him. Hear His Word. Let all that is within you also bow before Him.
