It can make a real difference in your life if you'll remember Psalm 24:1: "The earth is the Lord's, and all its fullness, the world and those who dwell therein.' Because the earth is the Lord's we can turn it over to Him. What difference does it make/
First, it reminds us that we are stewards and not owners. No matter what we have, we are only stewards of it. God owns everything. He doesn't own just the cattle on a thousand hills; He owns the Cadillacs in a thousand garages! God owns what you possess, and if He doesn't want you to have it, you'd better get rid of it. That brings humility, not pride. You can't brag about what you have if God gave it to you. John the Baptist said, "A man can receive nothing unless it has been given to him from heaven" (John 3:27).
Second, it makes us victors and not victims. The world doesn't belong to the devil. God has given him a certain amount of authority and freedom, but the earth is the Lord's. Jesus, not satan, is on the throne of heaven.
Third, it causes us to praise and not to complain. I like the repetition at the end of this psalm: "Lift up your heads, O you gates! And be lifted up, you everlasting doors!" (v. 7). "Lift up your heads, O you gates! Lift up, you everlasting doors! And the King of glory shall come in" (v. 9). Nothing will lift up one's head like realizing that God is in control. He's the King of glory. Wherever He rules, there will be grace and glory. If you want that kind of blessing, just remember that the earth and all its fullness is the Lord's. It doesn't belong to you; it belongs to Him, and He is in control.
Good stewardship is one of the great responsibilities of the Christian. You need to maintain a humble attitude toward what God has given you. Make sure you submit to His control. His generosity and grace are great blessings that make you victor.
