At the conference I attended in Thailand, there was quite a lot of discussion about living under grace versus the law. As Christians, we humbly and gratefully accept God’s grace in our life. Almost immediately, we set about doing everything we humanly can to keep it. And helpfully pointing out to others where they can improve, as well.
Case in point, Romans 3:23. I’ve heard this verse quoted a million times like this: “For all have sinned and fall short of the glory of God.” Period. We legalists quote this verse to prove to people that they’re sinners. Everyone is… see here, the Bible says so. When actually, that verse ends in a comma, and the very next phrase is, “and are justified freely by his grace through the redemption that came by Christ Jesus.” (We don’t so much quote that part.) Maybe because it actually gives almost the opposite message as verse 23 out of context.
In the words of Greg Koukl, you should never read a Bible verse. Always read a paragraph, maybe a chapter or even more – to make sure you understand the context.
