The emergent church has mixed up the mission of the church. Instead of sharing gospel the idea is to solve social justice problems and make life better - yet the world is dying and they are not hearing the gospel.
We can live a life of knowing we are saved - this helps conquer many self inflicted psychological problems - self image, respect esteem...all can be resolved in finding your salvation and identity in Christ
We are overwhelmed in life and find that its too hard to go on sometimes. Yet there is hope ! Life is in some ways a puzzle to solve. Once its solved your life is resolved.
