Psalm 11 talks about the wrath, fire and judgement of God.
I have some 3/4 formed thoughts about how the Psalm points to Jesus. But I would be delighted for blog readers to add their thoughts to the mix, as I prepare to preach it this Sunday. You can go in the footnotes that all good preachers put into their sermons and read out as people are exiting the building.
To the choirmaster. Of David.
11:1 In the Lord I take refuge;
how can you say to my soul,
“Flee like a bird to your mountain,
2 for behold, the wicked bend the bow;
they have fitted their arrow to the string
to shoot in the dark at the upright in heart;
3 if the foundations are destroyed,
what can the righteous do?” 
4 The Lord is in his holy temple;
the Lord’s throne is in heaven;
his eyes see, his eyelids test the children of man.
5 The Lord tests the righteous,
but his soul hates the wicked and the one who loves violence.
6 Let him rain coals on the wicked;
fire and sulphur and a scorching wind shall be the portion of their cup.
7 For the Lord is righteous;
he loves righteous deeds;
the upright shall behold his face.
 11:3 Or for the foundations will be destroyed; what has the righteous done?
After the first line, which really functions as a heading for the Psalm, it’s split into two, and you can imagine it as a dialogue going on between someone asking the Psalmist: “why don’t you run?!” (verses 1-3), and the Psalmist’s response: “I don’t think so!” (verses 4-7).
There is plenty to talk about here: situations we fear; the kindness and wrath of God; his steadfastness and dependability for good (if we are with him) and for ill (if we oppose him). But because I am trying to think about what it is about the Psalm that is particularly Christian, as opposed to Jewish, let me suggest three ways in which what David wrote is all about Jesus.
1. David himself is someone who is like Jesus.
My reasoning here is a bit fiddly and detailed, and were this anything more than a blog post I’d say a bit more. But basically it boils down to this: When I read the Old Testament I ask of the people I’m reading about, “how is this person like Jesus?” And whenever I read about David (as in, “A Psalm of David”, for example) I breathe a great sigh of relief, because the answer is easy. How is David like Jesus? Answer, “very much indeed, except for the bit where he had sex with his neighbour’s wife, murdered the neighbour, hunted his own son to an accidental death, and spent his old age keeping himself warm in bed with young women”. So that apart form the ways in which David is like us, he is like Jesus. Yes, I know, another blog post required there, but let Isaiah 11:1-5 provide the hint that David the Son of Jesse is a lot more like Jesus than he sometimes appears.
In this Psalm, David’s Christlikeness is spelt out by his faith in God: “In the Lord I take refuge”.
2. Second way this Psalm is about Jesus, is that he is—in some sense too awful to contemplate—‘the wicked’. For it is the eternally spotless and sinless Lord Jesus who receives the hot coals of fire and the stink of sulphur poured down upon his head at the time of his death. “Fire and sulphur and a scorching wind shall be the portion of their cup”, says David of the wicked. When Jesus prays in Gethsemane that his Father would remove this cup from me, it was exactly this cup—the cup of God’s anger—that Jesus experienced on the cross, in our place.
3. The third way this Psalm is about Jesus: precisely because Jesus receives on the cross the fiery cup of scorching coals and sulphur, he can now be the Lord in whom “I take refuge”. Jesus experiences in himself the fate that the wicked deserve, so that we might not have to. “For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God.” (2 Corinthians 5:21)
So a Psalm about a man on the run becomes a Psalm about the man to whom we can run for rescue.
