Taking up your cross and following Jesus will cost you literally everything. The price of eternal life is fulfilling your purpose in life and in the process of that goal you will have to lay everything on the altar of sacrifice, even your own self. You cannot hold anything or anyone back from God because he is a jealous God who requires our complete unadulterated love. Your life is no longer your own, but it was bought with a price, the shed blood of the Lord Jesus Christ.
Opposition is a natural consequence of following Jesus. Opposition comes at you from all directions, from familiar faces and unfamiliar faces, from those you love and from those you don't even know. Just because you decided to live your life according to the Word of God you have awakened hell and the hounds of hell are searching you out trying to sequester you, to isolate you, trying to surround you, and keep you from obeying the will of God by any means necessary.
The whole idea is to undermine your strength of purpose much like one who is determined to destroy a bridge by a continuous assault trying to ascertain a weakness that will bring the whole thing down.
That is the goal of your enemies to turn you into a feast for their decayed souls who feed upon those who have allowed their souls to decay and their spirits to die, like carrion hunting the souls of men for a prey; men and women who have sacrificed their eternal life for irrelevant things, and the few years remaining in this life, and all the sideways detours of pleasure down the jagged road to hell.
Whatever you see with your eyes is of very little consequence in the whole scheme of things. What does it matter how you live, where you live, what you eat or don't eat, wear or don't wear?
This life is but a momentary blip on the face of eternal existence, it is but a determining factor, a decision-making process that will come to a conclusion, that being where you will spend eternity, either in the presence of the Lord Jesus Christ, or in the presence of the evil one, Satan the fallen archangel who evidently lacked common sense.
Common sense tells us what we ought to do, and what we ought not to do, especially as it relates to the will of God. David comes to mind. He was king over all of Israel. He had a whole kingdom at his disposal, as many wives and concubines than one man can adequately handle.
He ruled his kingdom according to his will, yet he came to a point in time where he demonstrated a sheer lack of common sense, which led to adultery and murder. Consequently, the death of his first child by Bathsheba, the death of his son Absalom, the rape of his daughter Tamar, and the death of his son Absalom because he tried to usurp his father's kingdom, all because David's common sense just up and ran away from home.
