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.
