Armour of God

Eph 6:10-20

10 Finally, my brethren, be strong in the Lord, and in the power of his might.

11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.

12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.

13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.

14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;

15 And your feet shod with the preparation of the gospel of peace;

16 Above all, taking the shield of faith, wherewith ye shall be able to quench 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 thereunto with all perseverance and supplication for all saints;

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

20 For which I am an ambassador in bonds: that therein I may speak boldly, as I ought to speak. (KJV)

The words "put on" in verse 11, the words "take unto" in verse 13, are both in the aorist imperative which indicates a once-and-for-all action, not a continuous or repetitive action.

Rom 13:12

12 The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light. (KJV)

We are to "cast off" sin and "put on" good deeds as though they are protective Armour for battle. As Paul explained in Eph 6:10-17, this Armour of light represents all the features that make up God's gift of justification by faith. (See also: John 12:36; Eph 5:8; 1 Th 5:4-5; 1 John 1:7, 2:10)

So the teaching that the Armour must be prayerfully put on daily is not true in light of the passage.
