Alone in a world of unbelievers?

My tears have been my meat day and night,
while they continually say unto me, Where is thy God?
When I remember these things, I pour out my soul in me:
I will say unto God my rock, Why hast thou forgotten me?

Why art thou cast down, O my soul?

and why art thou disquieted within me?

hope thou in God:

Psalm 42:3.4,9,11
