Going Deeper with the Weekend Message

If you want to go deeper regarding the ethics of in vitro fertilization, a good start is an article from Christianity Today called "Souls on Ice."

If you want to go deeper with the whole of idea of God requiring a redemption for the firstborn sons, as well as more material on the Abraham and Isaac story, listen to one of my favorite all-time messages by Tim Keller called "The Story of the Lamb" (much of this material is also found in Counterfeit Gods chapter 1, but I think the message is masterful).
