I think when Adam and Eve ate the forbidden fruit humans then got a good side and a bad side. I think our flesh is the part of us that is prideful and wants to be God and it is our bad side and our spirit is the part of us that is surrendered to being a child of God - our good side and is how we are supposed to be.
When you feed your flesh you are building your ego and doing things to build your ego and your bad side that wants to be God.
When you feed your spirit you are doing what God wants and you are also growing spiritually. You are learning more about God and Christianity.
Am I wrong about any of this? What are your thoughts? I want to learn more about this and Christianity.
Those who walk in the flesh have their minds set on the things of the flesh. The mind of the flesh is death. Those who walk in the Spirit have their minds set on the things of the Spirit. The mind set on the things of the Spirit is life and peace.
Never walk according to your emotions or desires of your flesh.
