Each individual, who through a spiritual rebirth has been joined to Christ, is now engaged in a war. It is a war against (1) the natural, human nature that is subject to the passions of the material and sensory world pulling one toward self-gratification and away from serving God and others, and (2) actual spirit-beings who inhabit the world of darkness and who, while perhaps giving upon capturing our souls for eternity, try to discourage us an nullify our effectiveness for God.
There is no avoidance of this conflict. Those who reject God’s great sacrifice have capitulated and, whether they realize it or not, are already captives of their natural self and the spiritual forces in conflict with God. Believers in Christ have the privilege of battle-and victory!
God has many wonderful promises for those who overcome. Plus, he has given us the means: His presence and help, and the gift of faith.
"This is the victory that overcomes the world, our faith."
And remember all of our previous discussion about the Passover Lamb and His blood? The last book of the Bible speaks of our overcoming and, apparently in retrospect, speaks of how we secured victory over Satan and the things that would otherwise destroy us:
"And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death."
