The breastplate of righteousness is our defence against evil. The opposition to temptation is best carried on by the positive cultivation of good. A habit of righteous conduct is itself a defence against temptation. Untilled fields bear abundant weeds. The used tool does not rust, nor the running water gather scum. The robe of righteousness will guard the heart as effectually as a coat of mail. The positive employment with good weakens temptation, and arms us against evil. But so long as we are here our righteousness must be militant, and we must be content to live ever armed to meet the enemy which is always hanging round us, and watching for an opportunity to strike. The time will come when we shall put off the breastplate and put on the fine linen 'clean and white,' which is the heavenly and final form of the righteousness of Saints. A SOLDIER'S SHOES 'Your feet shod with the preparation of the gospel of peace.'--Eph. vi. 15. Paul drew the first draft of this picture of the Christian armour in his first letter. It is a finished picture here. One can fancy that the Roman soldier to whom he was chained in his captivity, whilst this letter was being written, unconsciously sat for his likeness, and that each piece of his accoutrements was seized in succession by the Apostle's imagination and turned to a Christian use. It is worth noticing that there is only one offensive weapon mentioned--'the sword of the Spirit.' All the rest are defensive--helmet, breastplate, shield, girdle, and shoes. That is to say, the main part of our warfare consists in defence, in resistance, and in keeping what we have, in spite of everybody, men and devils, who attempt to take it from us. 'Hold fast that thou hast; let no man take thy crown.' Now, it seems to me that the ordinary reader does not quite grasp the meaning of our text, and that it would be more intelligible if, instead of 'preparation,' which means the process of getting a thing ready, we read 'preparedness,' which means the state of mind of the man who is ready. Then we have to notice that the little word 'of' does duty to express two different relations, in the two instances of its use here. In the first case--'the preparedness of the Gospel'--it states the origin of the thing in question. That condition of being ready comes from the good news of Christ. In the second case--'the Gospel of peace'--it states the result of the thing in question. The good news of Christ gives peace. So, taking the whole clause, we may paraphrase it by saying that the preparedness of spirit, the alacrity which comes from the possession of a Gospel that sheds a calm over the heart and brings a man into peace with God, is what the Apostle thinks is like the heavy hob-nailed boots that the legionaries wore, by which they could stand firm, whatever came against them. I. The first thing that I would notice here is that the Gospel brings peace.
