(11) Spirit-filled men will be warriors, clad in the whole armor of God; if not Spirit-filled they could not carry it (ver. 11).
(12) Spirit-filled soldiers will not be warring against flesh and blood; internal foes having all been subdued, the civil war has ceased; their enemies are now external, and they are free to concentrate all their attention and God-inspired energies on them. Their enemies are (1) in the world—principalities and world-rulers, and (2) in the heavenlies—powers and spiritual hosts of wickedness (ver. 12).
(13) Spirit-filled men will be praying always in the Spirit (ver. 18). In order to this vigilance is necessary "watching thereunto."
Such are some of the results, on the positive side, of being filled with the Spirit. The effects on the negative side are manifest in Gal. v. 16, 17, "Walk in (by) the Spirit, and ye shall not fulfill the lust of the flesh. For the flesh lusteth against the Spirit, and the Spirit against the flesh; for these are contrary the one to the other: that ye (walking by the Spirit) may not do the things that ye would" (if ye were walking by the flesh). (See Gal. v. 19-21.)
3. Reaching the masses.
Another effect of a Spirit-baptized Church would be that the masses would be reached. See how the early Church—which was a Spirit-baptized Church, and persistently kept that truth in the foreground—reached the masses, and with what blessed results! They were not amused or entertained, but they were converted, saved, turned to the Lord.
