Some men are constitutionally more exposed than others to these interior assaults. There are conditions of the brain and nerves, tendencies lying deep in the organism, that give points of vantage to the enemy of souls. These are the opportunities of the tempter; they do not constitute the temptation itself, which comes from a hidden and objective source. Similarly in the trials of the Church, in the great assaults made upon her vital truths, historical conditions and the external movements of the age furnish the material for the conflicts through which it has to pass; but the spring and moving agent, the master will that dominates these hostile forces is that of Satan. The Church was engaged in a double conflict--of the flesh and of the spirit. On the one hand, it was assailed by the material seductions of heathenism and the terrors of ruthless persecution. On the other hand, it underwent a severe intellectual conflict with the systems of error that were rooted in the mind of the age. These forces opposed the Christian truth from without; but they became much more dangerous when they found their way within the Church, vitiating her teaching and practice, and growing like tares among the wheat. It is of heresy more than persecution that the apostle is thinking, when he writes these ominous words. Not blood and flesh, but the mind and spirit of the Asian believers will bear the brunt of the attack that the craft of the devil is preparing for the apostolic Church. III. The last clause of verse 12, _in the heavenly places_, refuses to combine with the above description of the powers hostile to the Church. The heavenly places are the abode of God and the blessed angels. This is the region where the Father has blessed us in Christ (i. 3); where He seated the Christ at His own right hand (i. 20), and has in some sense seated us with Christ (ii. 6); and where the angelic princedoms dwell who follow with keen and studious sympathy the Church’s fortunes (iii. 10). To locate the devil and his angels _there_ seems to us highly incongruous; the juxtaposition is out of the question with St Paul. Chapter ii. 2 gives no real support to this view: supposing “the air” to be literally intended in that passage, it belongs to _earth_ and not to heaven.[165] Nor do the parallels from other Scriptures adduced supply any but the most precarious basis for an interpretation against which the use of the exalted phrase in our epistle revolts.
