The fact that the Bible describes the Christian life as the good “fight of faith” (1 Timothy 6:12) reveals that the believer’s warfare is spiritual and never fleshly. In like manner, the enemy lives within the spiritual realm and this battle cannot be seen with the eyes of flesh. The enemy does not simply reside in a country on the other side of the world. In fact, it is no person or people group on this earth. Believers are told that they do not wrestle “against flesh and blood.” Ultimately, the saints’ enemy is the Devil, but his minions include principalities, powers, the rulers of the darkness of this world, and spiritual wickedness in high places. This means that the saints should never look to flesh and blood (mere mortals) for the source of their frustrations or victories. The fight is one of faith; the enemy, the Devil and the Lord our spiritual Captain (Hebrews 2:10).
Joy and peace! Any sensible person would readily admit his desire for a life filled with joy. Yet, few people understand the prerequisites for regularly living that way. Previous studies mentioned several of joy’s accompanying virtues, but today’s passage provides one of joy's unifying properties. According to our passage, peace accompanies joy. Proverbs 12:20 also expresses this same relationship: “Deceit is in the heart of them that imagine evil: but to the counsellors of peace is joy.” Those who seek peace will often find joy in this life because peace and joy are entwined. Isaiah 55:12 restates this truth: “For ye shall go out with joy, and be led forth with peace.” It is important to note that men will not “go out with joy” unless they are first “led forth with peace.” Peace and joy are always inseparable. Those who have the peace of God after they are at peace with God through salvation will experience "joy unspeakable" (1 Peter 1:8).
