Let me encourage you to take a moment and email him. I already did today. As President of the International Mission Board of the Southern Baptist Convention, he could always use our prayers and support. However, during such a time as this, he could use as much encouragement and support as he can get.
I know that during these last few months, as an evacuee from New Orleans, I have benefitted greatly just knowing that people care about me. My spirits are always raised when I know people are praying for me. I suspect he would feel the same right now.
If you are uninformed about the situation with Dr. Rankin, the following links to here, here, and here should provide some background into what is going on. Most of the time I'm proud to be a Southern Baptist. On rare occasions, and this is one of them, I am almost ashamed.
