A biblical perspective of stewardship is that of using and managing all the resources God provides for God's glory and the betterment of God's creation. Stewardship is not only about money. It is about managing all that God has provided, from our time and skills to our finances. The emphasis of biblical stewardship is on why we give - not how much or of what.
Ultimately, stewardship is a form of worship. When we give, we are not giving to a church or a charity. Instead, we are giving back to God what God has already provided us.
