Ephesians 6:18

Praying always - The apostle does not put praying among the armor; had he done so he would have referred it, as he has done all the rest, to some of the Grecian armor; but as he does not do this, therefore we conclude that his account of the armor is ended, and that now, having equipped his spiritual soldier, he shows him the necessity of praying, that he may successfully resist those principalities, powers, the rulers of the darkness of this world, and the spiritual wickednesses in heavenly places, with whom he has to contend. The panoply, or whole armor of God, consists in,

1. the girdle;

the breast-plate;

the greaves;

the shield;

the helmet; and

the sword. He who had these was completely armed.

And as it was the custom of the Grecian armies, before they engaged, to offer prayers to the gods for their success, the apostle shows that these spiritual warriors must depend on the Captain of their salvation, and pray with all prayer, i.e. incessantly, being always in the spirit of prayer, so that they should be ever ready for public, private, mental, or ejaculatory prayer, always depending on Him who can alone save, and who alone can destroy.

When the apostle exhorts Christians to pray with all prayer, we may at once see that he neither means spiritual nor formal prayer, in exclusion of the other. Praying, προσευχομενοι , refers to the state of the spirit as well as to the act.

With all prayer - Refers to the different kinds of prayer that is performed in public, in the family, in the closet, in business, on the way, in the heart without a voice, and with the voice from the heart. All those are necessary to the genuine Christian; and he whose heart is right with God will be frequent in the whole. "Some there are," says a very pious and learned writer, who use only mental prayer or ejaculations, and think they are in a state of grace, and use a way of worship far superior to any other; but such only fancy themselves to be above what is really above them; it requiring far more grace to be enabled to pour out a fervent and continued prayer, than to offer up mental aspirations." Rev. J. Wesley.

And supplication - There is a difference between προσευχη , prayer, and δεησις , supplication. Some think the former means prayer for the attainment of good; the latter, prayer for averting evil. Supplication however seems to mean prayer continued in, strong and incessant pleadings, till the evil is averted, or the good communicated. There are two things that must be attended to in prayer.

1. That it be εν παντι καιρῳ , in every time, season, or opportunity;

That it should be εν Πνευματι , in or through the Spirit - that the heart should be engaged in it, and that its infirmities should be helped by the Holy Ghost,

Watching thereunto - Being always on your guard lest your enemies should surprise you. Watch, not only against evil, but also for opportunities to do good, and for opportunities to receive good. Without watchfulness, prayer and all the spiritual armor will be ineffectual.

With all perseverance - Being always intent on your object, and never losing sight of your danger, or of your interest. The word implies stretching out the neck, and looking about, in order to discern an enemy at a distance.

For all saints - For all Christians; for this was the character by which they were generally distinguished.
