In 1 Chronicles 21:18 – 27  King David had numbered the people of nation of Israel.  David did this because Satan enticed him and because of this over 70,000 people died.  For David to be forgiven and to stop the angel from killing more David bought the threshing floor of Ornan and made a great sacrifices to God.

Christianity cost the death of Jesus Christ and it will cost you your spiritual life because you must die to sin and buried by immersion for the forgiveness of your sins.
