The following are John Wesley’s 4 questions from his sermon The Use of Money.
(1.) In expending this, am I acting according to my character? Am I acting herein, not as a proprietor, but as a steward of my Lord’s goods?
(2.) Am I doing this in obedience to his Word? In what Scripture does he require me so to do?
(3.) Can I offer up this action, this expense, as a sacrifice to God through Jesus Christ?
(4.) Have I reason to believe that for this very work I shall have a reward at the resurrection of the just?
You will seldom need anything more to remove any doubt which arises on this head; but by this four-fold consideration you will receive clear light as to the way wherein you should go.
