I always hear people talking about how they want to hear "Well done, good and faithful servant" at the judgment. Which most people use to imply that they have been good Christians therefore, they are worthy of eternal life. But the Holy Spirit through Paul said in Acts that those who are unworthy are those who think they are worthy and reject the righteousness of God in Christ Jesus. (Acts 13:44-46)
Your righteousness is not your own. I hope that when I do something good, I don't even know I'm doing it. That is freedom. Anything else is from the tree of knowledge of good and evil (self) and not from the Tree of Life (Jesus).
