Psalm 2:10-12 (ESV)
10 Now therefore, O kings, be wise;
be warned, O rulers of the earth.
11 Serve the Lord with fear,
and rejoice with trembling.
12 Kiss the Son,
lest he be angry, and you perish in the way,
for his wrath is quickly kindled.
Blessed are all who take refuge in him.
In the beginning of Psalm 2, David points out that the kings of the earth are against the Lord and his "anointed". David recognized the true authority of God and advises the kings and rulers of the world, as well as their subjects, to "kiss the Son, lest he be angry." The act of "kissing the Son" would be one of homage to a king, and would indicate submission to the kingship of the Son. Those who are wise will do so before the Son, the Messiah, comes to judge the world!
Men have often tried to appear holy and righteous before other men - but God is seeking those who will worship Him in "spirit and in truth".
In the 17th century, Fenelon was the court preacher for King Louis XIV of France. On one particular Sunday when the King and his attendants arrived at the chapel for the regular service, there was no one else present except the preacher, himself.
"What does this mean?", King Louis demanded.
"I had published that you would not come to church today, in order that your Majesty might see who serves God in truth and who flatters the King," Fenelon replied.
Let's be sure that our worship of God is true and faithful and that we aren't trying to please men in doing so. Serve the Lord with a Godly reverence for who He is, and what His Son has done for you, since He is worthy of your worship, and... He is looking at your heart.
Dear Lord, help our worship be true and faithful to You. Help us to serve You with the reverence that You deserve. In the Name of Jesus, Amen.
