In the warfare against the “spiritual wickedness in high places” (Eph. 6:12), prayer is a distinct weapon, a part of the armor of God. Prayer, the last mentioned piece in the armor, is the active expression of the essential principle of the conflict, namely, dependence. Man has no strength against Satan, and in nature he is Satan’s willing slave. The Christian’s resource is to lay hold upon a strength which is divine and which alone can cope with the power of Satan.
E. J. Thomas
