Time for the second Psalm! This one is a little longer than the first one, but it is very short to some later on. I have separated it into four parts, so make sure to look for the red to see where the Bible's words are separate from my own!
1 Why do the nations conspire
and the peoples plot in vain?
2 The kings of the earth take their stand
and the rulers gather together
against the Lord
and against his Anointed One.
3 "Let us break their chains," they say,
"and throw of their fetters."
This Psalm tells of how people do not truth the Lord, and consider him their imprisoner rather than the saving grace that He truly is. Those who want power want to 'overthrow' the most powerful of them all: God! They want to be 'free' of the Lord - to do whatever they wish - when he is in fact loving and protecting them all the way, even when they reject Him for their own selfish means.
4 The One enthroned in heaven laughs;
the Lord scoffs at them.
5 Then he rebukes them in his anger
and terrifies them in his wrath, saying,
6 "I have installed my King
on Zion, my holy hill."
When those on earth believe themselves to be better than God, he laughs - verse four even says he scoffs at their high and mighty behavior. They think that they are the best, until the Lord shows them who is really in charge. He can place whomever he wants on the throne, as he has shown many times before. The people believe that they can shed the Lord, when they really have no power over Him in the least; He has all the power in the world, while they hold none.
7 I will proclaim the degree of the Lord:
He said to me, "You are my Son;
today I have become your Father.
8 Ask of me,
and I will make the nations your inheritance,
the ends of the earth your possession.
9 You will rule with an iron scepter;
you will clash them to pieces like pottery."
God said to the people on earth basically to love Him. He said that he was the Father, and the people are his 'Son' (this is not limited to guys, it is used to describe every person). He promises here and many other places in the Bible that He will protect and provide for his people if only they would lay down their lives for Him.
10 Therefore, you kings, be wise;
be warned, you rulers of the earth.
11 Serve the Lord with fear
and rejoice with trembling.
12 Kiss the Son, lest He be angry
and you be destroyed in your way,
for His wrath can flare up in a moment.
Blessed are all who take refuge in Him.
The only time that we will ever have true peace is in the Lord. Here he tells the earthly kings to love their Lord more than anything else - even power - or risk His wrath. It is often said that our God is a jealous God; this doesn't mean that he wants something he can't have, but rather that He truly wants us. He runs to us and we just need to reach out a hand to receive His love. The people at this time are more in love with power than with the Lord, and this angers Him. He wants them to love Him more than anything else, and all who love Him and take refuge in Him are blessed.
