If God is the Owner, I am the manager toward the assets He has entrusted to me. Therefore, I needed to adopt a steward's mentality toward the assets. A steward manages assets for the owner's benefit. The steward carries no sense of entitlement to the assets he manages. It's His job to find out what the Owner wants done with His assets, then carry out His will.
Whenever we think like owners, it's a red flag. We should be thinking like stewards, investment managers, always looking for the best place to invest the Owner's money. At the end of our term of service, we'll undergo a job performance evaluation: "For we will all stand before God's judgment seat . . . So then, each of us will give an account of himself to God." (Romans 14:10, 12)
Giving interjects an eternal dimension into the most ordinary day. God owns everything. I am God's money manager here on planet earth.
