It's wonderful to climb the liquid mountains of the sky. Behind me and before me is God and I have no fears.

The image of “liquid mountains of the sky” evokes clouds as vast, shifting peaks—suggesting ascent into a realm that is both sublime and unstable. The line frames that ascent not as reckless daring but as spiritually grounded courage: with God “behind” and “before,” the speaker imagines divine presence as surrounding protection and guidance, dissolving fear. Read in light of Keller’s public persona as a figure of perseverance, the quotation resonates as a declaration that inner faith can transform daunting, even vertiginous experiences into wonder. Its power lies in joining sensory imagination (mountains, sky, motion) to a theological assurance that steadies the self.
