I just watched three sermons on comparing ourselves to others by Andy Stanley. You can access all three parts using the link below. At the very least, be sure to check out the first minute of each part where you can see a funny skit about comparison and trying to one up one another.
Here are my favorite quotes from the sermons:
1) There’s no “win” in comparison.
2) Whose does your heavenly Father compare you too? (No one)
3) Have you ever noticed that we compare ourselves to other people’s “highlights” reel?
