The heart of God must be in the center, not our stuff. Through simple belief we are justified and made complete in God's righteousness. Then as we begin our Sanctification we sense the death of our old self and learn more of His rest and peace. The eternal treasures which we discover from following Jesus. We can't manufacture this on our own. In prayer, bodylife and worship our hunger and desire to keep Christ in the center is ever increasing. 

Matthew 6: 21, 25 and 28
