The Greek translation for the phrase 'sound mind', suggests a mind that is delivered, rescued, revived, and protected, and is now safe and secure. This means, whenever you are tempted to give into fear, you can call on the Holy Spirit and the truth of God's Word to keep your mind secure and grounded in peace. When your mind is guarded by the Word of God, you think differently. It safeguards your emotions; defends your mind from demonic assault; and it shields you from negative, fear filled thoughts. All we need to do is discipline ourselves to spend time in God's Word to build our faith that has the power to overcome fear. And as we yield to the Holy Spirit, He floods our hearts with God's perfect love which casts out all fear.
