Let us then venture to lift this more accurate description into our text, "Put on righteousness like a coat of mail, wear it in all your comings and goings in the city of Ephesus, and in it meet all the malicious antagonisms of devils and of men." Now I wonder how the apostle's counsel affected these fearful struggling Christians in Ephesus. Let us look at them. Let us assume that we are with them, and that we are about to give them the counsel offered in the text. How will they receive it? Remember that they have just been lifted out of the horrible pit and out of the miry clay of long-continued sin, and that they are oppressed by their own weakness and helplessness, and by the strength of the evil inclinations and habits which they have just renounced. Well, now, let us offer these inexperienced disciples the apostle's counsel: "Put on righteousness like a coat of mail!" Why, they just look at you in utter despair! It is their very weakness that they cannot forge and weave such a coat of mail to cover them in the day of battle. The counsel would surely seem like the taunting cry of the foe.
Suppose we had waylaid poor Christian in "The Pilgrim's Progress" when he was struggling with his oppressive burden up the hill, and with the fiery darts of the devil hurtling around him on every side, and suppose we had called out to him, "Put on righteousness like a coat of mail!" We should surely only have added heaviness to his burden and crushed him to the ground in despair. "Put on righteousness like a coat of mail?" he would have moaned in his reply, "My righteousness is like unto filthy rags!"
One poor, sorrowful correspondent wrote to me some weeks ago who was the victim of alcohol and drugs. For years he had walked in ways of uncleanness, but he was now just waking from his awful sleep and turning his thoughts toward home. Suppose now I had written to him and said "Put on righteousness like a coat of mail!" I think his eyes would have dulled into weariness again, and he would have slipped back to his drugs and his despair. This cannot be the meaning of the apostle's counsel, or this coat of mail would never be worn.
What, then, does the apostle mean when he says "Put on righteousness like a coat of mail"? Let us seek for light in his own life, for he is a soldier as well as a counsellor, and we shall find him following his own advice and wearing the armour which he recommends to others. Let us listen then to this word, and let us mark its significance; "Touching the righteousness which is in the law I was found blameless." That seems like an invincible protection. "Touching the righteousness which is in the law I was found blameless!" But there was nothing invincible about it. It was no more a coat of mail than an ordinary vest, and the devil smote through the defences a dozen times a day.
Listen again to the apostle when he has passed into the intimate friendship of Christ: "Not having a righteousness of mine own." Mark that; yea verily mark that;--"Not having a righteousness of mine own." This coat of mail he wears is not his own righteousness. Whose, then, is it? It is the righteousness of Christ. As Paul declares: "It is the righteousness which is through the faith of Christ, the righteousness which is of God by faith." The apostle is wearing the righteousness of Christ, and he wears it like a coat of mail, covering back and front, shielding him before and behind.
I want to pause a little there because we are very near one of the deepest mysteries in the gospel of grace, and I want to state the mystery as plainly as words can express it. This, then, is what the Scriptures state: The Lord Jesus Christ was absolutely righteous, so righteous that human imagination and human dream cannot conceive it excelled. His holy obedience was perfect. There was no rent in the vesture of His holiness. There was no frayed edge, there was no imperfect strand, there were no stains. "In Him was no sin." We must begin there.
