There are some Christians that think once you receive the Holy Spirit you will never be tempted to sin or ever fall to sin again. That is not true. But if you are a true Christian you will immediately repent if you do fall into sin, and you will out of remorse say in your heart to the Lord Jesus, "...As long as I live, I will never fall back into that sin again..." You will immediately ask for forgiveness and NOT go back. It is the dogs that go back to their vomit, not the redeemed.
