The section in Ephesians 6 relating to the armour of God is very interesting:
Ephesians 6:
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:
Vs 11 - Here we see that we are to put on the whole armour of God so that we may stand against the wiles of the devil.
Vs 12 mentions wrestling, in which we struggle not against flesh and blood, but against principalities, powers, ruler of the darkness of this world, against spiritual wickedness in high places.
Vs 13 again mentions the whole armour of God that we are to take to ourselves in order that we may be able to withstand in the evil day, and having done all, to stand.
Vs 14 again tells us to stand and then we read about the various implements of the armour of God we are to put on. The armour of God listed consists for the most part of protective gear which enables us to stand and withstand as we preach the gospel.
So, we get through to vs 17 and now we're armed with the whole armour of God that we may stand and withstand. And what are the next instructions given to us ...
Ephesians 6:
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.
Pray and make known the Gospel (boldly as we ought to speak).
I just love this section of Scripture. Arm yourself with the whole armour of God ... now stand, withstand, pray, and boldly speak the Gospel.
And when we boldly speak the Gospel and pray, we will definitely find we need the whole armour of God. The spiritual wickedness in high places cannot stand against the power of the Word of God. And we also know that God does not leave us alone to face His adversary. He goes before us. He goes behind us. He goes beside us. Just as He led the children of Israel as they wandered in the wilderness, He leads us in this present evil day.
