I just recently re-discovered Last Days Ministries (Melody & Keith Green). Here's a link to their website, and a great tract on
Gossip written by Melody Green. Also, check out many more tracts in the
Article Index of tracts. By the way, there are some great pro-life tracts listed on the page.
They also have an Online Store for purchasing books, CD's, DVD's, song books, tracts, etc.
