Billy Graham's Answer
Christians aren't perfect. Every Christian sins, and every day those of us who are Christians need God's forgiveness and grace. I often think of the Bible's words: "If we claim we have not sinned, we make him (God) out to be a liar" (1 John 1:10).
But when someone claims to be a follower of Jesus and yet makes no effort to obey God and shows no evidence of a changed life, they may be deceiving themselves. The Bible is clear: When we know God, our lives will be different. Yes, our old sinful nature still lives within us, but God also lives within us by His Holy Spirit, and we won't be content to live the way we once did. Jesus said, "Thus, by their fruit you will recognize them" (Matthew 7:20).
