It takes a certain amount of ingenuity to invoke the not-too-sacred name of Carly Rae Jepsen in a sermon based on the 24th chapter of Joshua:
God doesn’t operate on a “Hey, I just met you/This is crazy” basis. And that means we need to learn a little bit. Not everything. If someone asks us about the hypostatic union of the divine and human in Christ, we’re still free to say, “Gesundheit.” But we need to know something about Jesus’s message of how our relationship with God is broken, but God’s grace in Jesus heals it.
(Link added mostly because I couldn’t remember the details of “hypostasis” well enough to comment upon it.)
