In today’s verse, “spirit” is the mental disposition that defines and characterizes the Christian’s faith. Our faith is not timid. Contextually, Paul encouraged Timothy to be bold in his “genuine faith” and unafraid to use the miraculous spiritual gift he had received (2 Tim. 1:5-6; 1 Tim. 4:14). He was duty-bound to use his gift with the power, love, and a sound mind. A sound mind is disciplined, exercising self-control in all things. Let us discipline our minds and bodies with self-control to choose godliness and resist evil (1 Cor. 9:24-27; Gal. 5:23). Otherwise, we tarnish and defile the gifts, abilities, and opportunities God gives us (Rom. 12:3-8). A bold faith disciplines itself with the power of God’s truth and love. The power of truth defines and guides our path, while love shapes our motives and objectives. When these combine with a disciplined mind, we are equipped with the confidence of faith not easily overcome by the world (1 Jno. 5:4).
