We had a great message at church on Sunday describing what it means to be a faithful steward. I encourage you to take a look here:
Matthew 25:23
Psalm 24 tells us that the earth and everything in it belongs to God. That includes everything we have. Our resources (possessions or "stuff"), abilities (talents), time, and even our trials are not really ours to do with as we please. They are things God loans to us to teach us something important. A faithful steward sees everything he or she has as a gift from God and manages it in a way that honors Him.
Where have you seen God's grace in your life today?
