Good Friday - Ransom and Redemption

This sermon series describes four views of the cross. Not that any of these views totally invalidates the others, but that each adds depth and sparkle to the others. The death of Christ on the cross cannot be explained by one metaphor. This week's sermon begins in Mark 10:45 and discusses how Christ came to serve and offer himself as a ransom. How is ransom different a judicial approach to the cross?
