For the director of music. Of David the servant of the Lord. He sang to the Lord the words of this song when the Lord delivered him from the hand of all his enemies and from the hand of Saul. He said:
I love you, Lord, my strength.
The Lord is my rock, my fortress and my deliverer;
my God is my rock, in whom I take refuge,
my shield and the horn of my salvation, my stronghold.
I called to the Lord, who is worthy of praise,
and I have been saved from my enemies.
I ran across a lecture by one of the best Old Testament evangelical scholars, Tremper Longman III, entitled, “God is a Warrior: Coming to Terms with Divine Violence in the OT.” If you have any interest in this subject at all, it’s well worth your time. And it grapples with something of the heart of the same issue which Greg Boyd works on in his The Crucifixion of the Warrior God and the concise version of that, Cross Vision: How the Crucifixion of Jesus Makes Sense of Old Testament Violence.
A major point I took away from it, was that the violence undertaken in the Old Testament was limited in scale and quite purposeful in intent, ordinarily God’s judgment. The main point for me being that those of Israel engaged in such, had to prepare themselves according to what God prescribed, so that in a certain sense they were set apart by God to participate in something of God’s work (my own way of expressing it).
Of course in this age the only warfare Christians can be involved in, as Tremper Longman III made clear is spiritual, against forces and entities not human, opposed to God, to the gospel, and to humankind. Although Longman sees an argument for Christians serving in the police force and the military. And how when Christ returns, something of that ban will be lifted, when Christ subdues all the enemies of God and humanity, perhaps even with just the breath of his mouth.
The main takeaway, or direct application for me here is this: We are in a spiritual battle and undertaking, for sure. And we need to go about it according to what God prescribes for us in scripture, for us in Jesus, in the New Testament. But how we need all of scripture, the Old Testament as well, maybe in ways we can’t understand at times, but like here, in ways which can help us understand what God’s people should do, what we’re to do. And it encouraged me to see the Old Testament, and specifically passages which we may not easily track with as “a message to be understood,” rather than “a problem to be solved.”
Psalm 18 therefore is not to be relegated to some lesser status, even if supposedly inspired scripture, according to Boyd. While it was of a different era, it has direct bearing on us today. In and through Jesus.
