You're blessed when you've worked up a good appetite for God. He's food and drink in the best meal you'll ever eat. Matthew 5:6 (MSG)
Contentment is a state of mind and heart. I know this because there are folks who live in what we would consider abject poverty who are perfectly happy. I have seen children with Down's syndrome laughing hysterically. I was greeted yesterday in Walmart by a young man with cerebral palsy and a big smile on his face. What a great gift to be satisfied because therein is peace.
An unsatisfied soul makes everyone miserable. It really is a state of mind and heart. It signals internal corruption when all we can do is complain.
God fulfilled His righteousness in Jesus and as the body of Christ we are called to not only seek righteousness, but to pursue it. In this way we will find satisfaction- as we help transform the culture and glorify His name.
