There is a war within the human soul that trusts in Jesus as their Lord. That battle is between our fallen sinful nature that we are born into and the new nature given to us by Christ Jesus when we become born again believers. Paul admonishes us to “live by the Spirit and you will not gratify the desires of the sinful nature.” Just as a certain tree bears certain fruit, so too does our life when we allow either of our two natures to influence us most. If the fallen nature, we will exhibit sinful acts. If we allow the Spirit of God to rule us then we will bear the fruit of the Spirit listed in Galatians chapter 5.
