Romans 12:1-8 -- Paul gives the call to the church in Rome to live by the light of the new day. The new day, for Paul, is the dawning of the day of the Lord; this will be the completion of the work of Jesus Christ already begun--to bring God's Reign in fullness for all.
So how do we live by the light of the new day? Where do we begin?
Often this task is simplified, which isn't all bad, but leaves us short of our calling. We begin with understanding the "mercies of God." When we embrace and surrender to God's mercy we can then begin to live a life in response to that mercy. Mercy changes everything...from the inside out.
By the "renewing of our mind" we are "transformed" as human beings.
Are we ready to be renewed? Even from where we are right now? Even if it takes us where we cannot possibly imagine?
This is faith, my friends.
