There’s another fine critique of Calvinism, and especially the idea of double-predestination (God pre-ordains who will go to heaven and who will go to hell), over at Evangel blog. Read it here. This one’s by Adam Omelianchuk; a few months ago I linked to two similar posts on the same topic (here and here; my response here, and general thoughts on Calvinism here) by Anthony Sacramone. Again, it’s nice to be reminded that there are plenty of Christians who do not believe that God wants people to go to hell.
