It can make a real difference in your life if you will remember some Psalm 24:1. 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. 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.
Good stewardship is one of the great responsibilities of the Christians. Make sure you submit to His control: His generosity and Grace are great blessing that make you a victor.
