The Apostle Paul has much to say about the flesh.
It has been said that the flesh is fallen human nature under the power of sin.
Soldier of The Cross, the Blood of Jesus executed the old nature according to God's Word. We live in a fallen world and choices must be made. But you are no longer helpless or under the power of gravities that do not align with God's Word.
The flesh is a distraction and those who would follow the Lord need to understand there is no room for resentment, the need for attention, passivity, the seeking of comfort or the exalting of self.
The world is desperately looking for His Life. Life that cares about others first. Life that loves unconditionally. Life that ministers Grace. Life that flows no matter what.
Soldier, why would you not choose whatever He says is best? You know you can't go back. You must go forward. We who know Him understand that we are preparing for eternity until we draw our last breath. How deeply do you care about others.
The whole world is looking for love.
Go!
