In Psalm 86:11, David prayed, "Teach me your way, LORD, that I may rely on your faithfulness; give me an undivided heart, that I may fear your name."
God made all things and owns all things. As owner, He has full rights to rule over everything and everyone and to evaluate the actions of all of the creatures He owns (including me). His rule and evaluation extend both deep and wide. In width over all existence. In depth over my actions, my words, my thoughts, and even my nature. David, rather than rebelling against God's control of his own heart, relished the thought and asked that the Sovereign Lord gracious grant him an undivided heart so that he might fear God alone and not men. Naturally, no man from his sinful heart chooses God. It takes God's mighty and tender hand to soften our naturally stony hearts, so that we will want to trust and follow him. That is why Jesus said to Nicodemus "No one can see the kingdom of God unless they are born again," (John 3:3). Instead of objecting against God's rightful role as King and Judge, we ought to come humbly to our good and gracious King, asking to be granted a heart to know and love Him fully. God through your indwelling Holy Spirit illuminate in my mind your words, reveal my false thinking, and convict me to repent. In my heart make your words precious to me, reveal my sinful desires, and convict me to repent. Take hold of my will until I submit to you wholly and joyfully. I love you Lord.
