Offered a free threshing floor, free oxen, and free wood for the altar, David refuses with a sentence that measures every offering since: I will not sacrifice to the LORD my God burnt offerings that cost me nothing.

In Acts, Peter owns no silver or gold and gives a lame man something better. Today is about what we offer God and others, and what it costs. Bring your wallet and your calendar to the reading; they are spiritual documents.

David's refusal at Araunah's floor names a law of worship: love that costs nothing communicates nothing. He paid full price for ground he could have had free, and on that costly ground the temple would rise, and nearer still, Calvary's costlier altar. Grace is free to us precisely because it was not free to God.

Peter's empty pockets preach the same economics from the other side: he had no money, but he had spent himself on Jesus, and so had power worth more than alms. Audit your offerings this week, the giving that pinches nothing, the serving that risks nothing, and choose one thing to offer that actually costs. That is where the fire falls.
