Scripture calls us to be grateful. It does *not* call us to idleness. So where does ambition fit in? I Corinthians 7:21 tells us that we may be called while being a servant, and that that's ok. It also says "if you can be free, then do so". Our physical bodies were built to need both dopamine (desire, drive) and seratonin (gratefulness, satisfaction). Take time to thank the Lord for what you have, and then get up and labor to grow and steward it even better.
