I have found that in seeking to understand life’s circumstances, there is always a need to balance spiritual and natural truth. The spirit side refers to the spiritual or the unseen realm, while the truth refers to the natural or seen realm.
John 4:23-24 says, “But the hour is coming, and now is, when the true worshipers will worship the Father in spirit and truth; for the father is seeking such to worship Him. God is Spirit, and those who worship Him must worship in spirit and truth.”
Think of it this way. A road has two ditches, one on each side of the road. Focus solely on the spiritual side and you will end up in the ditch. Focus solely on the natural side and you’ll end up in the other ditch. In both cases you’re stuck with no way out.
Not everything that happens to you is spiritual and not everything is natural. The fact that your car ran out of gas is not an attack of the devil. You just forgot to fill the tank. The reason you’re experiencing sickness is not necessarily hereditary, it may be an attack from the devil.
I encourage you to study and learn to discern the spiritual from the natural. It’s important to understand the difference. My book, If God Is In Control, Then Why, will help. I explain this more thoroughly in chapter 9, Spirit and Truth.
