Jim Elliff is president of Christian Communicators Worldwide. He recently wrote an article concerning church membership, a topic he feels very passionate about, focusing on Southern Baptists in specific - with application to other denominations as well. It's worth the read.
(HT - Justin Taylor) Justin writes a lot of good stuff - well worth your time reading what he has to say. He presents info about arguments sometimes used in the abortion discussion here, and here, and a bit about poetry as well!
