Psalm 2:11-12 Serve the Lord with fear, and rejoice with trembling. Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him.
Instead of rebelling and raging against the Lord, our response to God in our life should be love, service, rejoicing, submission, and trust. The rebellious kings of the earth includes all of us. God is wrathful against His sinful and rebellious created humanity. He will send His Son who will break them in pieces at the Judgment, but He will also bear upon himself our deserved punishment. Either way, all sin and rebellion will be judged either on Jesus or on us.
Therefore a Holy God is to be feared (worshipped and believed). And those who believe the Son will serve (love) Him, who has taken away the punishment. They will rejoice with trembling (feeling). They will kiss (an act of worship and submission). They will be blessed because they put their trust in Him. They trust Him because they know He has died for them, taken their judgment, forgiven their sins, and earned for them eternal life. Blessing follows.
The very Son who sits in just judgment is the very One who died for us. When the Spirit grants such faith through the Gospel we naturally respond with service, rejoicing, and submissive worship.
