Ephesians 6:11 Put you on the armour of God, that you may be able to stand against the deceits of the devil. 12 For our wrestling is not against flesh and blood; but against principalities and power, against the rulers of the world of this darkness, against the spirits of wickedness in the high places. 13 Therefore take unto you the armour of God, that you may be able to resist in the evil day, and to stand in all things perfect. 14 Stand therefore, having your loins girt about with truth, and having on the breastplate of justice, 15 And your feet shod with the preparation of the gospel of peace:
 "In the high places"... or heavenly places. That is to say, in the air, the lowest of the celestial regions; in which God permits these wicked spirits or fallen angels to wander.
16 In all things taking the shield of faith, wherewith you may be able to extinguish all the fiery darts of the most wicked one. 17 And take unto you the helmet of salvation, and the sword of the Spirit (which is the word of God). 18 By all prayer and supplication praying at all times in the spirit; and in the same watching with all instance and supplication for all the saints: 19 And for me, that speech may be given me, that I may open my mouth with confidence, to make known the mystery of the gospel. 20 For which I am an ambassador in a chain, so that therein I may be bold to speak according as I ought.
1 Timothy 2:1 I desire therefore, first of all, that supplications, prayers, intercessions, and thanksgivings be made for all men: 2 For kings, and for all that are in high station: that we may lead a quiet and a peaceable life in all piety and chastity. 3 For this is good and acceptable in the sight of God our Saviour, 4 Who will have all men to be saved, and to come to the knowledge of the truth. 5 For there is one God, and one mediator of God and men, the man Christ Jesus:
[1 Timothy 2:] Ver. 4. "Who willeth that all men should be saved, and come to the knowledge of the truth."
Imitate God! if He willeth that all men should be saved, there is reason why one should pray for all, if He hath willed that all should be saved, be thou willing also; and if thou wishest it, pray for it, for wishes lead to prayers. Observe how from every quarter He urges this upon the soul, to pray for the Heathen, showing how great advantage springs from it; "that we may lead a quiet and peaceable life"; and what is much more than this, that it is pleasing to God, and thus men become like Him, in that they will the same that He does. This is enough to shame a very brute. Fear not therefore to pray for the Gentiles, for God Himself wills it; but fear only to pray against any, for that He wills not. And if you pray for the Heathens, you ought of course to pray for Heretics also, for we are to pray for all men, and not to persecute. And this is good also for another reason, as we are partakers of the same nature, and God commands and accepts benevolence and affection towards one another.
