We cannot prevent the three enemies of our souls from intruding upon us. There is the devil. He will come and go. But we can use God's word to thwart his ploys. Then comes our own sinful nature, the flesh, in which "nothing good dwells" (cf. Romans 7:18). This we must daily drown by contrition and repentance, remembering that we are baptized into Jesus' death and resurrection, remembering that we are no longer slaves to sin (Romans 6:1-6). But the world is all around us. And everywhere we turn it will seek to force us into its mold. Against that we must renew our minds (Romans 12:1-5).
Satan will come again for Jesus. Peter will be his messenger (cf. Matthew 16:13-23). But we must remember that Satan's days are numbered. And the daily troubles and tribulations we experience are nothing compared with the glory that will be ours through our Lord Jesus Christ (Romans 8:18). He has overcome Satan - despite his relentless attacks, innuendos, and schemes.
