I was in a store shopping for a sweater. The cost needed to be minimal, so I went to the clearance rack to start looking. As I flipped through the sweaters, one caught my eye. It was the right color and the right size, and best of all, the price tag was marked $8.00. Without much more thought, I made my purchase.

At home I slipped on the sweater. Its texture was like silk. I had made my purchase so quickly that I hadn't noticed how smooth and elegant the sweater was. Then I saw the original price tag: $124.00!

I gasped. I had never owned any clothing of that value. I had come home with what I thought was a "cheap buy," but the original price was quite high. I had been oblivious to its value.

Just as with my sweater, I have often treated the power of Jesus' blood like a "cheap purchase." His grace, though free to me, carried a high price tag, the life of his very own Son.
