Luke 12:23 (NIV) - 23 For life is more than food, and the body more than clothes.
Why do we wear ourselves out for those things that perish?
My wife and I were talking about this very thing last night, how you will never be content with more if you are not content with what you already have. You will always want more if you need more to be happy.
Learn to be satisfied with Christ and then even the smallest of God's blessings on this earth will bring you inward joy!
