Our knowledge of spiritual warfare and the proper mindset/attitude we need to have about our unseen war come from knowing God’s Divine Truths. That is why He provides us with at least 39 Bible verses/passages that either deal specifically with spiritual warfare or the godly attitude we need to have about the ways the devil is fighting us (God’s Children and Christ’s Soldiers) for our living souls—our minds, wills, desires, determinations, consciences, affections, emotions, personalities, five senses, common sense, and so on and so forth. In short, since we ARE living souls who HAVE living souls, we need to know and understand that the devil is after everything that pertains to our living souls (where the devil truly loves to operate; where he definitely loves to make his appeal to our emotions and affections—our fleshly lusts, desires, and appetites).
God already has performed this new heart transplant surgery on many of His children (on every born again and saved believer in Jesus the Christ), but He is not done. Indeed, He continues to be in the heart transplant business.
