Scripture teaches that everything we own – everything appointed for our benefit – has been given to us by God’s kindness, so that all that we own is like a deposit for which we must one day give an account. Therefore, we should manage our possessions as if these words were constantly sounding in our ears: “Turn in the account of your management” (Luke 16:2). At the same time, we should remember who will receive the account we give – namely, one who has commended self-control, soberness, frugality, and modesty just as much as He has condemned luxury, pride, showiness, and vanity; one who has approved no use of possessions but that which is joined with love; one who has already condemned with His own mouth whatever pleasures drag man’s heart away from integrity and purity or muddle his thinking.
John Calvin, A Little Book on the Christian Life (pg. 123).
