Psalm 23 and mission – Jesus as shepherd, host, Emmanuel

I came across this quote in McCann’s NIB commentary on the Psalms while preparing for an undergad module on Missional Texts: Psalms & Genesis 1-11

In short, in NT terms, Jesus is shepherd, host, Emmanuel. When Psalm 23 is heard in the context of Psalm 22 and of Jesus Christ, its profoundly radical implications are even clearer: God is with us, but is not ours to own; the God who shepherds us to life also gives life to the world; the table at which we are hosted is one to which the whole world is invited.
