(18, 19) And supplication for all saints; and for me.--It is curious, and probably not accidental, that the prepositions in these two clauses are different. The first is properly "touching all saints," and the second "on behalf of me." Both are often interchanged; but there is, perhaps, here a touch of greater earnestness in the request of their prayers for himself, in especial reference to the need which is spoken of in the next words.

Verse 18. - With all prayer and supplication praying. The metaphor of armor is now dropped, but not the idea of the conflict, for what is now insisted on is of the most vital importance for successful warfare. Though prayer is virtually comprehended in most of the previous exhortations, it is now specifically enjoined, and in a great variety of ways; "all prayer and supplication," equivalent to every form of it, e.g., ejaculatory, secret, spoken, domestic, social, congregational. At all seasons. No period of life should be without it - youth, middle life, old age, all demand it; no condition of life - adversity, prosperity, sunshine, desolation, under sore temptation, under important duty, under heavy trial, under all the changing circumstances of life, personal, social, Christian. See the hymn-

"Go, when the morning shineth;
Go, when the noon is bright;
Go, when the day declineth;
Go, in the hush of night." In the Spirit; for true prayer is spiritual, and it is not true prayer unless by the Holy Spirit the heart is filled with heavenward longings and aspirations, changing our prayer from cold form to heartfelt realities. The ordinary habit of the soul should be prayerful, realizing the presence of God and looking for his grace and guidance. And watching thereunto; that is, "towards" spirituality, against formality, as also against forgetfulness and neglect of prayer. Perhaps also the idea of watching for the answer is involved, as you wait for an answer when you have dispatched a letter. In all perseverance; this being very specially needed to make prayer triumphant, as in the case of the Syro-phoenician mother, or in that of Monica, mother of Augustine, and many more. And prayer for all saints; this being one of the great objects for which saints are gathered into the "one body" the Church, that they may be upheld and carried on, in warfare and in work, by mutual prayer, kept from slips and infirmities, and from deadly sins, and enabled one and all to "walk worthy of the vocation wherewith they are called."

6:10-18 Spiritual strength and courage are needed for our spiritual warfare and suffering. Those who would prove themselves to have true grace, must aim at all grace; and put on the whole armour of God, which he prepares and bestows. The Christian armour is made to be worn; and there is no putting off our armour till we have done our warfare, and finished our course. The combat is not against human enemies, nor against our own corrupt nature only; we have to do with an enemy who has a thousand ways of beguiling unstable souls. The devils assault us in the things that belong to our souls, and labour to deface the heavenly image in our hearts. We must resolve by God's grace, not to yield to Satan. Resist him, and he will flee. If we give way, he will get ground. If we distrust either our cause, or our Leader, or our armour, we give him advantage. The different parts of the armour of heavy-armed soldiers, who had to sustain the fiercest assaults of the enemy, are here described. There is none for the back; nothing to defend those who turn back in the Christian warfare. Truth, or sincerity, is the girdle. This girds on all the other pieces of our armour, and is first mentioned. There can be no religion without sincerity. The righteousness of Christ, imputed to us, is a breastplate against the arrows of Divine wrath. The righteousness of Christ implanted in us, fortifies the heart against the attacks of Satan. Resolution must be as greaves, or armour to our legs; and to stand their ground or to march forward in rugged paths, the feet must be shod with the preparation of the gospel of peace. Motives to obedience, amidst trials, must be drawn from a clear knowledge of the gospel. Faith is all in all in an hour of temptation. Faith, as relying on unseen objects, receiving Christ and the benefits of redemption, and so deriving grace from him, is like a shield, a defence every way. The devil is the wicked one. Violent temptations, by which the soul is set on fire of hell, are darts Satan shoots at us. Also, hard thoughts of God, and as to ourselves. Faith applying the word of God and the grace of Christ, quenches the darts of temptation. Salvation must be our helmet. A good hope of salvation, a Scriptural expectation of victory, will purify the soul, and keep it from being defiled by Satan. To the Christian armed for defense in battle, the apostle recommends only one weapon of attack; but it is enough, the sword of the Spirit, which is the word of God. It subdues and mortifies evil desires and blasphemous thoughts as they rise within; and answers unbelief and error as they assault from without. A single text, well understood, and rightly applied, at once destroys a temptation or an objection, and subdues the most formidable adversary. Prayer must fasten all the other parts of our Christian armour. There are other duties of religion, and of our stations in the world, but we must keep up times of prayer. Though set and solemn prayer may not be seasonable when other duties are to be done, yet short pious prayers darted out, always are so. We must use holy thoughts in our ordinary course. A vain heart will be vain in prayer. We must pray with all kinds of prayer, public, private, and secret; social and solitary; solemn and sudden: with all the parts of prayer; confession of sin, petition for mercy, and thanksgiving for favours received. And we must do it by the grace of God the Holy Spirit, in dependence on, and according to, his teaching. We must preserve in particular requests, notwithstanding discouragements. We must pray, not for ourselves only, but for all saints. Our enemies are mighty, and we are without strength, but our Redeemer is almighty, and in the power of his mighty we may overcome. Wherefore we must stir up ourselves. Have not we, when God has called, often neglected to answer? Let us think upon these things, and continue our prayers with patience.Praying always with all prayer and supplication in the spirit,.... The last weapon is prayer, and takes in all sorts of prayer, mental and vocal, public and private; and every branch of it, as deprecation of evils, petitions for good things, and thanksgiving for mercies: and which should be used always: this stands opposed to such who pray not at all, or who have prayed, but have left it off; or who pray only in distress, and it suggests, that a man should pray as often as he has an opportunity; and particularly, that he should make use of it in times of darkness, desertion, and temptation: and this, when performed aright, is performed "in the Spirit"; with the heart, soul, and spirit engaged in it; it is put up with a true heart, and a right spirit, and without hypocrisy; in a spiritual way, and with fervency, and under the influence, and by the assistance of the Spirit of God.

And watching thereunto; either to the word, as a direction for prayer, or to prayer itself; for opportunities to pray for the assistance of the Spirit in prayer, for an answer of it, and to return thanks for blessings when bestowed; and against all dependence on it, and against Satan's temptations, and our own corruptions with respect to it:

with all perseverance; in it, notwithstanding what Satan and an unbelieving heart may suggest to the contrary:

and supplication for all saints; of every nation, age, sex, and condition, in all places, and of every denomination. So Christ taught his disciples to pray, saying, our Father, suggesting, that they were not only to pray for themselves, but for all the children of God.
