Psalm 132 is a testament to David's devotion to God, even through the hard times.
The writer asks God to remember all the hardships that David endured, and how David remained devoted towards finding a place for the Holy Temple of God. David vowed that he would not enter his own house or his own bed, would not sleep or even rest his eyes until he found a dwelling place for the Lord.
David searched high and low, and found the place for the House of the Lord in the fields of Jaar. The people asked God to enter His resting place, both God and the Ark of the Covenant. The priests would be clothed with God's righteousness, and all the saints would shout for joy. They pleaded with God to enter the Holy Temple for the sake of His servant, David.
God had given David a solemn oath, and God keeps His Word. God said that one of David's sons would be set upon David's throne, and if they keep God's covenant, God would keep them upon the throne.
God had chosen Zion for His dwelling place. He said it would be His resting place forever. God said that He would abundantly bless them, giving provisions to the poor. Their priests would be clothed with salvation, and the saints would shout for joy.
Finally, the writer, not knowing fully what he was writing about, proclaimed Jesus Christ. "There will I make a horn to sprout for David; I have prepared a lamp for my anointed. His enemies I will clothe with shame, but on him his crown will shine."
As Christians, we should ask ourselves: Have we opened our hearts to God to give him a resting place in the new temple, our bodies? Are we proud that He chose these bodies as temples? Do we pray daily for God to remain in His temple, our bodies, so that we can shine for Him? Are we clothed with shame, or are we gems in His crown shining before all?
