Ephesians 6:12

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.

Ver. 12. Not against flesh and blood] Hereby the apostle meaneth not so much the corruption as the weakness of our natures, q.d. We have not only to conflict with weak, frail men, but with puissant devils. Look to it therefore, and lie open at no place; but get on every piece of this spiritual armour, whether those of defence (as the girdle of truth, breastplate of righteousness, the shoes of peace and patience, the helmet of hope), or those of offence, as the sword of the Spirit, and the darts of prayer. Fetch all these out of the Holy Scriptures, which are like Solomon's tower, where hang a thousand shields and all the weapons of strong men. The apostle here soundeth the alarm, crying, Arm, arm, &c.

But against principalities] So wicked men make the devils, by being at their beck and obedience. Observe here, saith an interpreter, in the Holy Ghost a wonderful pattern of candour: he praiseth what is praiseworthy in very enemies. How then shall not the saints be accepted and acknowledged, since they sin not of malicious wickedness, as devils do?

Against spiritual wickedness] Gr. πνευματικα της πονηριας, The spirituals of wickedness, those hellish plots and satanical suggestions, black and blasphemous temptations, horrid and hideous injections, &c. Whereby he seeks to dispirit and defeat us, by setting before us the difficulties of Christian warfare; like as some inhospitable savages make fearful delusions by sorcery upon their shore, to fright strangers from landing.

In high places] εν τοις επουρανιοις, or, about our interest in those heavenly privileges, which the devil would wring from us, and rob us of. He strove with the angel about the body of Moses; but with us about our precious souls. And herein he hath the advantage, that he is above us, and doth out of the air assault us, being upon the upper ground, as it were.
