Ephesians 6:18 Meaning and Commentary

Ephesians 6:18

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.

Ephesians 6:18 In-Context

16 Above all, taking the shield of faith, with which ye will be able to extinguish all the fiery darts of the wicked.

17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:

18 Praying always with all prayer and supplication in the Spirit, and watching for this purpose with all perseverance and supplication for all saints;

19 And for me, that utterance may be given to me, that I may open my mouth boldly, to make known the mystery of the gospel,

20 For which I am an embassador in bonds: that therein I may speak boldly, as I ought to speak.
