If you have ever seen a movie where someone gets demon possessed, you would have noticed a battle going on between the demon, who wants to take control of the person to make them do evil, and the person, who want’s their life back. Sometimes the demon possessed person is controlled by the demon. Sometimes the person is in control of their own body. Sometimes it’s a combination of both.
Although it sounds a little strange, something similar happens to a person when they become a Christian.
The Bible teaches that when a person places their life and eternity into Jesus hands, the Holy Spirit comes into their life to wage war against their sinful nature. In a sense, they get ‘Holy Spirit Possessed’. From that moment on, there is a battle that rages within between the Holy Spirit, who wants to take control of the person to make them more like Jesus, and the person’s sinful nature, which loves sin and craves sin. Sometimes the Holy Spirit is in control. Sometimes the sinful nature is in control. Sometimes it’s a combination of both.
This is why when you meet a Christian, you can definitely expect to see evidence that the Holy Spirit has come into their life. The Bible describes this as ‘fruit of the Spirit’: “love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control” (Galatians 5:22-23).
But this is also why you will unfortunately continue to see evidence of their sinful nature: selfishness, gossip, lust, greed, complaining, unforgiveness, bitterness, envy, etc.
“The sinful nature desires what is contrary to the Spirit, and the Spirit what is contrary to the sinful nature. They are in conflict with each other, so that you are not to do whatever you want”
