This post from Bob Kauflin is a fantastic idea about memorizing scripture through music. He offers those passages of scripture that their church put to music for download in this same post. I encourage you to go and check out this great tool.
Another tool for this, specifically with children is Seeds Family Worship. Click on both, and I highly encourage you to seriously consider purchasing these CD's. I want to personally thank one of my friends and accountability partners, Micah, for introducing me to these cd's, but also to Tim Challies for drawing my name from his virtual hat, leading to my winning the whole package of these cd's for my family.
