I loved this account of one pastor's putting a parable into action:
Pastor's Challenge Shocks Congregation
As soon as I saw a teaser saying that a pastor had handed out fifty dollar bills and made a challenge, I figured it was the parable of the talents. Very cool idea, releasing the ingenuity and creativity of the congregation.
What would you do if you were given fifty bucks and challenged to increase it many times over for charity in a short period of time?
