I subscribe to www.biblestudyplanet.com (really cool site, by the way) and the latest bible study posted was entitled "Christianity 101: Justification." Check it out here: http://biblestudyplanet.com/christianity-101-justification/. Studying this principle reminded me of a blank card I designed last year. I believe it too promotes the gift of justification that God has given to us through His Son, Jesus the Christ. Enjoy!
