Mark 12:30-31 declares that we are to love God with our heart, soul, mind and strength. The challenge for the believer is what theologians call the noetic effect of sin: 2 Corinthians 4:4 affirms the depths of sin’s effect on our minds. For that reason, one of the weighty commands of the New Testament is to “renew our minds” (e.g., Romans 12:1-2; Ephesians 4:23). Colossians 3:2 commands: “Set your minds on things that are above, not on things that are on earth.” In 2 Corinthians 10:5 Paul speaks of taking “every thought captive to obey Christ.”

John introduces Jesus, the Warrior Lamb of God.
