Again, note here what the armour is. Of course that phrase, 'the armour of light,' may be nothing more than a little bit of colour put in by a picturesque imagination, and may suggest simply how the burnished steel would shine and glitter when the sunbeams smote it, and the glistening armour, like that of Spenser's Red Cross Knight, would make a kind of light in the dark cave, into which he went. Or it may mean 'the armour that befits the light'; as is perhaps suggested by the antithesis 'the works of darkness,' which are to be 'put off.' These are works that match the darkness, and similarly the armour is to be the armour that befits the light, and that can flash back its beams. But I think there is more than that in the expression. I would rather take the phrase to be parallel to another of this Apostle's, who speaks in 2nd Corinthians of the 'armour of righteousness on the right hand and on the left.' 'Light' makes the armour, 'righteousness' makes the armour. The two phrases say the same thing, the one in plain English, the other in figure, which being brought down to daily life is just this, that the true armour and weapon of a Christian man is Christian character. 'Whatsoever things are true, whatsoever things are lovely, whatsoever things are of good report,' these are the pieces of armour, and these are the weapons which we are to wield. A Christian man fights against evil in himself by putting on good. The true way to empty the heart of sin is to fill the heart with righteousness. The lances of the light, according to the significant old Greek myth, slew pythons. The armour is 'righteousness on the right hand and on the left.' Stick to plain, simple, homely duties, and you will find that they will defend your heart against many a temptation. A flask that is full of rich wine may be plunged into the saltest ocean, and not a drop will find its way in. Fill your heart with righteousness; your lives--let them glisten in the light, and the light will be your armour. God is light, wherefore God cannot be tempted with evil. 'Walk in the light, as He is in the light' ... and 'the blood of Jesus Christ cleanseth from all sin.'
