2 Timothy 1:7

For God did not give us a spirit of timidity or cowardice or fear, but (He has given us a spirit) of power and of love and of sound judgment and personal discipline (abilities that result in a calm, well-balanced mind and self-control).

One of the reasons we have to renew the mind every day is because it doesn’t stay renewed without our continued reading of the Bible. Keeping the word fresh before our eyes every day keeps back fear and keeps our minds focused on the promises of God. We are to discipline ourselves, our thoughts, and our feelings. We choose to walk in faith or fear. Choose faith.
