And of a sound mind” means God has given us a self-controlled and self-disciplined spirit against every confusion and panic that comes in any fearful situation. He has given us control over every ugly situation or obstacle on our path that is hindering the gift of God in our life or for progress. Sound mind or self-control is the work of the dwelling Spirit of God in us. The Spirit detests sin, strives to please God, thinks and acts with wisdom, and reorganizes our shattered lives.
