Psalm 2 shows us that God gave David and his descendants the task of carrying out his redemptive purposes in the world. The Psalm also looks to the future messiah, David's ultimate heir Christ Jesus who would accomplish this.
1 Why do the nations conspire and the peoples plot in vain?
2 The kings of the earth rise up and the rulers band together against the LORD and against his anointed, saying,
3 “Let us break their chains and throw off their shackles.”
4 The One enthroned in heaven laughs; the Lord scoffs at them.
5 He rebukes them in his anger and terrifies them in his wrath, saying,
6 “I have installed my king on Zion, my holy mountain.”
7 I will proclaim the LORD’s decree: He said to me, “You are my son; today I have become your father.
8 Ask me, and I will make the nations your inheritance, the ends of the earth your possession.
9 You will break them with a rod of iron ; you will dash them to pieces like pottery.”
10 Therefore, you kings, be wise; be warned, you rulers of the earth.
11 Serve the LORD with fear and celebrate his rule with trembling.
12 Kiss his son, or he will be angry and your way will lead to your destruction, for his wrath can flare up in a moment. Blessed are all who take refuge in him.
For you and I the reality of leaving behind the futility and sin of this world is not far away. So do not lose heart!
