Based on the accounts of the Word of God, there’re just two ways people can live. The first one is according to the flesh, and the second one is according to the Spirit. The first thing to remember is that by nature we’re predisposed to live according to the flesh as a result of our fallen nature which we’ve inherited due to the fall of man. By the way, it doesn’t take that much sacrifices and efforts to live according to the flesh because all you really have to do is to follow the sinful desires found within you. To put it differently, living according to the flesh comes naturally.
