Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
Stand therefore,.... Keep your ground, do not desert the army, the church of Christ, nor his cause; continue in the station in which you are placed, keep your post, be upon your watch, stand upon your guard:
having your loins girt about with truth; by which is meant the Gospel, and the several doctrines of it; see Ephesians 1:13; and to have the loins girt with it, shows, that it should be near and close to the saints, and never departed from; and that it is a means of keeping them close to God and Christ, and of strengthening them against the assaults and attacks of Satan; and is of great use in the Christians' spiritual conflict with their enemies; the girdle is a part of armour, and so considerable as sometimes to be put for the whole, Isaiah 5:27; and here it is mentioned in the first place:
and having on the breastplate of righteousness; in allusion to
Isaiah 59:17, meaning not works of righteousness done by men, though these are a fence when rightly used against the reproaches and charges of the enemy, as they were by Samuel, 1 Samuel 12:3, but rather the graces of faith and love, 1 Thessalonians 5:8, though faith has another place in the Christian armour, afterwards mentioned; wherefore it seems best to understand this of the righteousness of Christ, which being imputed by God, and received by faith, is a guard against, and repels the accusations and charges of Satan, and is a security from all wrath and condemnation.
