Take Heart!

Psalms 138:8 (RSV)

The LORD will fulfill his purpose for me; thy steadfast love, O LORD, endures for ever. Do not forsake the work of thy hands.

Each one of has a purpose in life that we should try to live out guided by God's love in us and for us. When we emulate Jesus actions and life, we can rest assured that we are following God's will. When we emulate the faith of Christ, I think we find purpose in life.
