Tim Challies at www.challies.com has produced a wonderful infographic illustrating the Reformed understanding of the Ordo Salutis. What is the Ordo Salutis? Tim gives an explanation here, but in short, the term refers to the logical sequence of the steps of salvation. Click on the picture for a high quality pdf version. I am thinking about getting this printed and mounted for instructional purposes. FedEx can do high quality poster for about $45. A mounted poster is twice that. Not cheap, but would be a useful visual.
