" To work we are entitled, but not to the fruits thereof." Said a great Soul once. Duty with detachment is the key. Point here is that attachment is the problem, being slaves to things. If we can offer them up to the Lord in the spirit of selflessness, remembering that all belongs to Him, then where is the problem?
Simple things; material things are all tools we use. It is infinitely more important to get out hearts right with Him then see what follows. Peace.
