Tears and Rain Meaning ???

The song for me is weird. . It seems that James Blunt is having a hard time. He's trying to seek for real comfort.. as i read its lyrics...its sounds like having a less destination in life.. He doesn't know where he is, what he's going through... that he doesn't know the meaning of life... all i can say is "LIFE is GOD" = i mean, the purpose why we are here on earth is to see and feel GOD'S GOODNESS..and live to GLORIFY HIS NAME!!! There's a verse that states : LET EVERYTHING THAT HATH BREATH PRAISE THE LORD.
