Christians are not immune to sin. The sin nature is still very real even after a person is saved. In Romans, Paul admits his own struggle to live for God. Sometimes you know something is wrong, but you just can’t quit. For some it may be the more obvious things like alcohol addiction, cigarette addiction, pornography addiction, etc. For others, it may be what may be referred to as personality traits like a short temper, moodiness, or worrisome. Or maybe it’s a sharp tongue, unforgiveness, or a multitude of other things. Whatever it is, Satan desires to use it to turn you completely away from God but God has made a way for you to be delivered and completely set free.
When Jesus died on the cross, He paid the way for everything that we have need of, including our deliverance.
When a person is saved, becomes a Christian, this happens by doing nothing other than believing that Jesus died on the cross and paid the price for sin and accepting that. It is the same for deliverance. A person must just believe in what Jesus did on the cross. It doesn’t require a 12-step program or reading the latest book or participating in the latest program. In fact, not only does it not require those things but God hates these manmade efforts at righteousness. God has made the way, through Jesus, and this is the way to deliverance.
The sin nature remains even after a person is saved. However, through faith in Jesus and His sacrifice, a Christian can have victory over that sin nature and the sins that bind us. A Christian should not remain a bound person. God has something better.
Believe Him and receive it.
For sin shall not have dominion over you: for you are not under the Law, but under Grace.
