I've spent a good deal of time in this essay; I've probably posted two-thirds or more of it online. I hope it moved you as much as it has me. In my opinion, this essay shows Heschel at his best. He exemplifies the deep yearning of humanity for intimacy with God, yet he also reflects the hesitancy we feel to approach the throne of grace.
Because he wasn't a Christian, he didn't have the same assurances that Christians have, but I daresay he knew God better than most Christians do! We have the assurance that we can "boldly approach the throne of grace," as Hebrews puts it. Yet, we rarely do it. We're too enamored by the mere triffles of living in the twenty-first century post-modern, social media-saturated, materialistic (in the metaphysical as well as physical senses) world. We are practicing atheists.
May we repent and believe the good news of God's presence before it is too late!
