Here are a couple blog posts I recommend:
David Sills, on his blog Culturality and Missiology, has posted a compelling essay that deserves wide readership. I strongly encourage you to read "Has Anybody Seen Our Missionary Heroes?" May we live up to the standard set in this post. May God raise up a generation of missions leaders.
Also, Larry Baker has posted preliminary findings presented by Chuck Lawless on the habits of pastors of high impact churches. The official report will be released this spring. The findings may not surprise you, but they may convict you. Read the post here.
