Mind
God has given us minds to make decisions, think great thoughts and control our lives. But our minds are not only ours to control. They can be controlled by our sin or by the Holy Spirit. If our intellect is controlled by sin, we will make poor decisions. If the Holy Spirit controls our minds, we live in a way that pleases God. We can actually have the "mind of Christ," which leads us to a greater relationship with him.

The mind controlled by sin is corrupt.
Romans 8:1-17
1 Timothy 6:5
2 Timothy 3:8
Titus 1:15
1 Peter 1:13

The mind controlled by the Holy Spirit finds peace.

Romans 8:5-6; 12:2
Philippians 4:7
Jesus Christ is our example.
1 Corinthians 2:16
2 Corinthians 10:1-10
