We are told in Colossians 1:10 to "live lives worth of the Lord". For many of us, that's a defeatist statement: how can we ever possibly be worthy of God? Others of us read that and decide we must earn our salvation. Our good works can easily be motivated either by fear or obligation. But Colossians reminds us that our salvation is free. That nothing we do can earn OR repay God's favor. We live Christian lives as a response to God's generosity and goodness. We respond out of joy. Nothing more, nothing less!
