Blood of Paradise

Shall our blood fail? Or shall it come to be
The blood of paradise? And shall the earth
Seem all of paradise that we shall know?
The sky will be much friendlier then than now,
A part of labor and a part of pain,
And next in glory to enduring love,
Not this dividing and indifferent blue.

For me this was the best part of the poem. I liked how Stevens uses the term "blood" to describe people and their religious view. I think "shall our blood fail?" the speaker of the poem wondering if her religious views are not going to lead to anything and she will just die like everyone or will religion or belief for that matter, bring her to paradise. Then he asks, "and shall the earth seem all of paradise that we shall know?" and I think this is a reference to the last lines where he says "and next in glory to enduring love, not this dividing and indifferent blue." I think he is trying to say that Paradise can be here on earth while one is living instead of just some kind of heaven or after life. I thought the term, "indifferent blue" refers to the sky with the intention of the earth being under the blue and heaven being above the blue. I thought indiffernt was an appropriate word because the speaker is asking whether religion is going to bring her to paradise or if her religion is going to fail her... I think. And if thats the case than this relates to after life, and will her religion save her and bring her to heaven or will it fail her and bring her to hell. Then the next component of this section of the poem, is will religion bring paradise to earth while living and eliminate the indifferent blue?

The part here that says that sky is much friendlier now from part labor and part pain I thought might relate to Christianity and their belief of Jesus and his pain that he endured while on the cross and the labor could be the faith and the church goes on Sunday mornings. Thats just my interpretation there, could be way off
