Divine Spiritual Connection Between Body and Spirit (Request for Sources)

With D&C 89 on the docket, I've been asked to give a talk in my ward this coming Sunday. (Short notice, back-filling some cancellations.) Assigned topic is:

How can taking care of our physical well being help us feel closer to the Savior?

To that end, I'm looking for reputable sources (scriptures, GC talks, etc) about the following:

• LDS teachings on the sanctity of the body, how different it is from the rest of Christianity, and why it matters so much
• The inextricable connection between our bodies and our spirits

I of course will be including the WoW promises in D&C 89, referencing that our body is the temple of God (1 Cor 6), but I've got a whole talk I need to give on the subject, and I'd rather fill it with doctrinal meat...in this case NOT sparingly, lolol
