We see three powerful truths that reinforce one another in our passages today. (1) In the passage from Deuteronomy 4, we see the God of perfection and power who has made his people his own. "No God has ever done anything like this before!" Indeed: of all the gods humanity has imagined in books of old, the legends and the myths, there's no one like our God, nor is there any rescue that compares to his redemption. (2) But this produces a problem: the people of God cannot live up to his holiness and perfection. The Israelites floundered in the wilderness of Sinai; the Corinthians floundered in the desert of a pagan city. Tempted to live paganish lives, they had in their midst.
(3) The solution is found in Psalm 22. The logical conclusion would be to forsake these wicked people completely—and indeed, that is what Deuteronomy and 1 Corinthians threaten. But Psalm 22 reveals that there is a forsaken one. On the cross, where Jesus cites the opening words of this Psalm, the perfect servant of God experienced forsakenness so that God's people in him would not be cut off.
And no one has ever seen a God like *that.*
So now God's people are called to lives of holiness in light of the great sacrifice that cleanses us: "Such were some of you; but you were washed, you were sanctified, you were justified."
