Mike Donehey of Tenth Avenue North has put together a 28 day devotional called "Living Alive" - www.livingalivebook.com
Here's more information about "Living Alive"
Living Alive is a 28-day reflect-to-action devotional, challenging readers to not only listen to the words of Jesus from his Sermon on the Mount but to also go one step beyond what’s comfortable by intentionally living them out.
This is not an "earn your salvation, look at my good works" sort of thing. This is not about trying to earn God’s approval but rather an exciting invitation to respond to the love that God that has already lavished upon you.
