Let's see, the classic chapter 6 of Ephesians is full of weapons against the devil. The Shield of Faith. I need something to guard my heart when my optimistic nature sours into dejection. A shield certainly sounds more substantial than a pair of tinted glasses. After all, my rosy glasses make ordinary surroundings look wonderful.
Faith is a different piece of equipment.
It's based on spiritual reality. Confidence in God and His word would have really helped her out at that turning point. Rose-colored glasses help us believe that the choir will sound terrific in their difficult choral piece, although practice went badly. Faith believes God will care for us even when our health is gone, the piggy bank is empty, and the roof is leaking. I must conclude that faith is a much sturdier piece of equipment than my rosy spectacles.
