Many Christians believe their salvation depends at least in part on their performance. Even though they believe that Jesus died for their sin, they think that there is still a certain standard to meet. If that is true, then what is the standard, and how do you know when you have met it?
When you understand the Apostle Paul's revelation in the book of Romans about what Jesus did, you will never have to wonder if you're meeting that standard again. It's not what you do but what Jesus did!
