But the believer has a new heart (Ezekiel 36:26), a new mind – even the mind of Christ (Romans 7:25; 8:26; I Corinthians 2:16), and new desires for things of God (Romans 7:18; II Corinthians 5:2; Hebrews 13:18). Yet, God’s work in this renewed heart is unfinished (I John 3:2). The mind can’t see as clearly as it will (I Corinthians 13:9, 12), the desires can be entangled (Galatians 2:11-13), and the will can’t fully do God’s will (Galatians 5:17). The flesh in the believer remains unsearchable and deceitful.
