Serve the Lord with fear and rejoice with trembling

Psalm 2
David is the son of God, God have begotten him. Kiss the Son, lest he be angry, and you perish in the way, for his wrath is quickly kindled.
David is the Lord's anointed one. They are against his anointed.
The nations rage and the people plot in vain.
Listen and be wise, be warned, all nation's rulers should serve the Lord with fear, and rejoice with trembling.
Blessed are all who take refuge in him.
Why?
God has authority in everything in the world, the anointed one is greater than anyone among people. No one can against the Lord's command.
Kiss his son, not only David but also Jesus Christ, means love Jesus Christ, lest be perish in the way.
Even God has revealed his word and love but many people still do not follow God's word and against the mighty God. Their way is forward to perish under God's wrath. God's wrath is God's righteousness be executed.
It is once again a reminder to all people, listen, be wise, be warned. Careful listen God's word, be warned to our sins, be wise to know the way of life.
Blessed are all who take refuge in the Lord Almighty.
Rejoice with trembling is joy but won't astray on the way of God, fear his righteousness and his authority. Somehow we may serve the Lord with our heart, and won't care the laws or tradition, it is right but our heart may astray when we don't sense it and sin against the Lord.
Wise: careful follow the word of God and repent our sin and wake up be ready.
How?
Bless are all who take refuge in him. Don't think I can do something, without the blessing of the Lord I can do nothing.
