Our Bible study group had never tried a LifeGuide study before, but very much enjoyed the series until the seventh lesson. From there, it took a very strong enviornmental position. We felt there was a definate agenda behind the lesson and that it read more into the Scriptures than what was actually there. The prayer at the close of the lesson actually stated that we should, "Pray for environmental scientists, that we will see more clearly the meaning of our human covenant with the earth." Isaiah 24 talks about the end times, Christ's return, and how HE will destroy the earth. We did not see how it had ANYTHING to do us making a "covenant with the earth." We believe the teaching is misguided and returned ours. Buyers beware.
