I recently finished reading 2 Samuel. Following David’s sin of numbering the people in 2 Samuel 24, the Lord executed judgment, but relented and had mercy upon David (2 Samuel 24:16). David was told to raise an altar to the LORD on the threshing floor of Araunah the Jebusite (2 Samuel 24:18). Araunah was loyal to King David. When David told him he needed to purchase his threshing floor, Araunah offered to give it to him as a manifestation of honor to the king. David’s response to this act of kindness provides us a tremendous insight for living lives pleasing to God: living the life of faith should be costly.
“Then Araunah said to David, ‘Let my lord the king take and offer up what seems good to him. Here are the oxen for the burnt offering and the threshing sledges and the yokes of the oxen for the wood.  All this, O king, Araunah gives to the king.’ And Araunah said to the king, ‘May the LORD your God accept you.’  But the king said to Araunah, ‘No, but I will buy it from you for a price. I will not offer burnt offerings to the LORD my God that cost me nothing.’ So David bought the threshing floor and the oxen for fifty shekels of silver” (2 Samuel 24:22-24, ESV).
May God keep us from presenting ourselves as cheap sacrifices (Romans 12:1-2) and may our faith be a costly one in a world that freely offers up cheap grace.
