Rap Redeemed

When God speaks through Asaph to John Piper to Shai Linne, you get a song called My Portion on The Solus Christus Project. Further hope that deep, foundational truths can be expressed in a compelling way through one of my favorite musical genres. However whitely I might be constrained to write about it, I'm beginning to see the prospect of rap as it should be... can I get a witness?
