Albert Barnes Commentary Ephesians 6:18

"with all prayer and supplication praying at all seasons in the Spirit, and watching thereunto in all perseverance and supplication for all the saints," — Ephesians 6:18 (ASV)

Praying always. It would be well for the soldier who goes out to battle to pray—to pray for victory, or to pray that he may be prepared for death, should he fall. But soldiers do not often feel the necessity of this.

To the Christian soldier, however, it is indispensable. Prayer crowns all lawful efforts with success and gives a victory when nothing else would.

No matter how complete the armor, no matter how skilled we may be in the science of war, no matter how courageous we may be, we may be certain that without prayer we will be defeated.

God alone can give the victory; and when the Christian soldier goes out armed completely for the spiritual conflict, if he looks to God by prayer, he may be sure of a triumph.

This prayer is not to be discontinued. It is to be always. In every temptation and spiritual conflict we are to pray .

With all prayer and supplication. With all kinds of prayer: prayer in the closet, the family, the social meeting, the great assembly; prayer at the usual hours, prayer when we are specially tempted, and when we feel just like praying ; prayer in the form of supplication for ourselves, and in the form of intercession for others. This is, after all, the great weapon of our spiritual armor, and by this we may hope to prevail.

"Restraining prayer, we cease to fight;
Prayer makes the Christian armor bright;
And Satan trembles when he sees
The humblest saint upon his knees."

In the Spirit. By the aid of the Holy Spirit; or perhaps it may mean that it is not to be prayer of form merely, but when the spirit and the heart accompany it. The former idea seems, however, to be the correct one.

And watching to this end. Watching for opportunities to pray, watching for the spirit of prayer, watching against all those things that would hinder prayer (See Matthew 26:38, Matthew 26:41).

(Compare 1 Peter 4:7).

With all perseverance. Never becoming discouraged and disheartened .

And supplication for all saints, for all Christians. We should do this:

1. Because they are our fellow believers—though they may have a different skin, language, or name.
2. Because, like us, they have hearts prone to evil and, with us, need the grace of God.
3. Because nothing tends so much to make us love others and to forget their faults as to pray for them.
4. Because the condition of the church is always such that it greatly needs the grace of God. Many Christians have backslidden, many are cold or lukewarm, many are in error, and many are conformed to the world; and we should pray that they may become more holy and may devote themselves more to God.
5. Because each day many a Christian is subjected to some peculiar temptation or trial, and though he may be unknown to us, yet our prayers may benefit him.
6. Because each day and each night many Christians die. We may reflect each night as we lie down to rest that while we sleep, some Christians are kept awake by the prospect of death and are now passing through the dark valley; and each morning we may reflect that today some Christian will die, and we should remember them before God.
7. Because we will soon die, and it will be a comfort to us if we can remember then that we have often prayed for dying saints, and if we may feel that they are praying for us.
