The world laughs at weakness, but Paul says it’s his secret weapon. When we are weak, then he is strong. Paul tells us to stand in the strength of the Lord, not in our might. There is no reason to be courageous if we must rely on our own abilities. Paul gives the image of the breastplate of righteousness to defend us against Satan’s attack. This is Christ’s righteousness, not our own. We can stand confidently, knowing we are accepted by Christ’s obedience, and fight against the darkness with his strength. We would never stand in our own ability to obey, but we have all the strength of the universe when we stand in God’s power, in Christ’s righteousness.
