Jesus Christ is the one who makes most sense of that Psalm and indeed of everything.
And while we're on the subject of nostalgia, Hebrews and Psalm 8 were right there at the start of this blog (eke and mild and Hebrews 13). Glad to know I haven't moved on from what is important, but, rather, I ought to have moved further into it. Like the fractals, I hope to be going round and round, not in circles of emptiness, but in spirals of ever-increasing richness. That's what growing up is about, and thus what growing up into Christ all the more so. And, of course, it can't be done without Christian brothers and sisters, so praise the Lord for the church, too.
