Lyric discussion by haulinoates 

The person the song is addressing is the devout Christian trying to live his life without sin, in order to establish the kingdom of heaven on Earth and in the hereafter (the setting sun).

He has been spending his whole life fighting other ways of life to establish his mode of life on earth. The third verse supposes that now the world is predominantly as he wants it, and still he is unhappy with the world that he made (still asking for the sun).

All the things he really wants are not in devout living, but in living SINFULLY, which is what he has been avoiding.

The chorus is both a mockery of his cry to God for absolution, and the Devil reaching out to him to cry for absolution to Him, not for remission of sins, but to forgive him of his sinlessness.
