Thank you for your feedback. I do understand your suggestion. Let me explain a little bit of why I chose the words I did. The first stanza is how the world sees me. The second stanza is how God sees me. This is the central part of the poem, because it is the most important. That is how I can say I am made perfect in his sight. Perfect means blameless, spotless, without stain or wrinkle. But the third stanza is how I see myself, and I know that I struggle with my sin nature. I fall short, and miss the mark all the time. And because I know that I fall short, and I struggle, when I see one of my brothers or sisters struggle with their sin nature, I try to remember that they struggle just like I still do. I try to reach out to them with love, compassion, and understanding, instead of judgment and legalism, and even then, sometimes I don't succeed.
It is a reminder for me that I am not perfect yet. And because I fall short of perfection, it is easier for me to be sympathetic when others fall short of perfection as well, whether they be unbelievers, or brother and sisters in Christ.
