That poem landed where much secular humanist poetry lands when it comes to death, and that is that it's okay to be pro-afterlife only if we can't know what that is. It's okay to entertain thoughts of life after death as long as the only surety is the anticipation of it and the possibility of what we might make of ourselves in the next life. But more importantly, the ideology goes, since we can't ever really know what will happen to us after we die, we are to close out our lives on earth having made sure that we have truly lived, to have given it our best shot here.
In contrast to this daring to think wishfully, the Christian can know the content and context of their next life. In addition, life that precedes that heavenly life is lived within that knowledge, not irregardless or in ignorance of it.
It is with unabashed surety in the joy of our salvation based on God's own Word to us that we live outside of a fear of death and free of hesitant maudlin musings in the genre of "perhaps."
God's gift of salvation in Jesus Christ is now, in present tense, and later, forever in heaven. That is a truth, not a conjecture; a sure hope, not a maybe; a firm foundation, not a crapshoot.
