Taking the Old Testament Challenge: A Daily Reading Guide

The Senior Pastor at a Grand Rapids-area WCA church wrote in to tell us:
"This last Sunday we began a church-wide emphasis called Old Testament Challenge. I am preaching through the Old Testament and our people are being challenged to read through the entire Old Testament. Small groups will also be going through the material. So far it is awesome to see the excitement. For example, some of the high school kids were talking to each other and expressed a desire to do the readings but admitted they didn't think they could be faithful without accountability. As a response, they spontaneously formed a small group among themselves to do the readings and get together weekly for accountability and discussion. (My daughter is one of the kids.) Is that awesome, or what!"
