The miracle is not that we do His work, but that we are happy to do it.
Don't do God's work because you feel you have to; rather, look at all the good that is coming from your service. Be happy that you are serving the One that has blessed you so generously.
Offer hospitality to one another without grumbling. Each one should use whatever gift he has received to serve others, faithfully administering God's grace in its various forms. If anyone speaks, he should do it as one speaking the very words of God. If anyone serves, he should do it with the strength God provides, so that in all things God may be praised through Jesus Christ.
