Atheism isn't a religion, because atheism does not require faith. It takes no faith at all to not believe in a god. It just takes a lack of evidence.
by George Herbert
Awake, sad heart, whom sorrow ever drowns ;
Take up thine eyes, which feed on earth ;
Unfold thy forehead, gathered into frowns ;
Thy Saviour comes, and with Him mirth :
And with a thankful heart His comforts take.
But thou dost still lament, and pine, and cry,
And feel His death, but not His victory.
Arise, sad heart ; if thou dost not withstand,
Christ's resurrection thine may be ;
Do not by hanging down break from the hand
Which, as it riseth, raiseth thee :
And with His burial linen drie thine eyes.
Christ left His grave-clothes, that we might, when grief
Draws tears or blood, not want a handkerchief.
