Certainly, a housekeeper can be seen as a steward over the cleaning and general upkeep of the house. A business manager serves in a position of stewardship as he oversees the business and financial affairs of his employer. A banker is a steward entrusted with the safe keeping of the funds deposited in his bank by his customers and clients.
Police officers and judges are stewards who serve to protect society through upholding the laws of the land. Governmental leadership positions such as mayor, governor, and president are positions of stewardship. Persons are elected to those offices to serve the general interests and well being of the people at large. A great many such examples of stewardship could be cited.
As Christians we are stewards in a number of capacities. We are stewards of our very lives. God has blessed us with life, and He expects us to glorify Him through the way we live (Romans 12:1; 1 Corinthians 6:19-20). We are stewards over the various blessings which God bestows upon us (James 1:17).

As Christian parents we are stewards over the precious children God has placed in our care. We must take care of them, love them, and raise them in God's love (Ephesians 6:4).
As Christians we are stewards of the church. We are the "body of Christ" (1 Corinthians 12:27). We must present to the world around us the proper image of what God has designed the church to be (1 Timothy 3:15). We must faithfully communicate the saving message of the gospel throughout the world, to all peoples (Mark 16:15-16).
Perhaps most fundamentally, we are stewards of our eternal souls. We have this time, while in this world, to prepare for eternity. However we use, or misuse, out time here will impact what eternity holds for us (Hebrews 9:27). We must not be careless stewards! Let us pray for God's guidance and wisdom and apply ourselves conscientiously in our various roles of stewardship...
