This document outlines a 10-week challenge to transform one's heart. It encourages praying daily for enlightenment and for God to search one's heart and make it like Christ's. It discusses monitoring what comes out of one's mouth as an indicator of one's heart. It also discusses identifying sources of impurity, exposing them to God, and eliminating them. The challenge is to monitor one's heart for mercy and desire for righteousness. The next week will examine what may be holding one's heart captive.
