Put on therefore the “armor of light” (Rom. 13:12). What a grand expression! Helmet of light, breastplate of light, shoes of light—everything of light. What a knight must one be who is clad in light! Like a wall of fire, the Lord’s appearings are around you; there ought to be a special glory of holiness in the midst. That is the position of the righteous, and it furnishes a call to holiness.
