John Wesley suggested this prayer before a purchase:
“Lord,
thou seest I am going to expend this sumer on that food, apparel,
furniture. And thou knowest I act therein with a single eye, as a
steward of thy goods, expending this portion of them thus, in pursuance
of the design thou hadst in entrusting me with them. Thou knowest I do
this in obedience to thy word, as thou commandest, and because thou
commandest it. let this, I beseech thee, be a holy sacrifice, acceptable
through Jesus Christ! And give me a witness in myself, that for this
labor of love I shall have a recompense when thou rewardest every man
according to his words.”

He was confident that any believer who has a clear conscience after praying this prayer will be using money wisely.
