Both of these pastors were Calvinists, meaning that they believed in predestination. Both would have said that God planned those accidents before he formed the Earth. I still believe that.
I miss my friends and I wish I had their guidance now. I'm sad for their wives and for the children that one of them left behind. But I know they're with Jesus in heaven now and I know that God loves and is caring for those they left behind, including me.
Here is one of their sermons (David), left as a ghost on an old Myspace page. The links to Dustin's last sermon are all broken, but I have the file on my computer and I have linked to it here if you'd like to listen to it. Both of their last sermons are on God's providence and sovereignty and urge us to trust God at all costs.
