The king shall have joy in Your strength, O LORD;
And in Your salvation how greatly shall he rejoice!
You have given him his heart’s desire,
And have not withheld the request of his lips. Selah
For You meet him with the blessings of goodness;
You set a crown of pure gold upon his head.
He asked life from You, and You gave it to him —
Length of days forever and ever.
His glory is great in Your salvation;
Honor and majesty You have placed upon him.
For You have made him most blessed forever;
You have made him exceedingly glad with Your presence.
For the king trusts in the LORD,
And through the mercy of the Most High
he shall not be moved.
This is a psalm about King David. But ultimately, it is a song about King Jesus, the Son of David. And it is also about all those who belong to Jesus through faith in Him (see A Tale of Three Kings in the Psalms).
Psalm 21 is a celebration of the victories God has given to the king. Indeed, they are the very victories that have established the king as king, for by them God has “set a crown of pure gold” upon the king’s head.
As we think of Jesus, the great victory that established His kingdom is found in the cross and the resurrection. By them, God has given Jesus the desires of His heart. Though He despised the shame, Jesus willingly endured the cross, because of the “joy that was set before Him,” and He has been seated at the “right hand of the throne of God” (Hebrews 12:2). The great humility of Jesus led to His great exaltation (see The Humble God-Man Exalted with the Highest Glory).
By resurrection from the dead, God has made Jesus, who was crucified for our sakes, both Lord and Messiah (Acts 2:36). That is, He showed Jesus to be the One whom God anointed as King over Israel and the nations. More than that, by the power of the resurrection, God has seated the Lord Jesus at the right hand of God, “far above all principality and power and might and dominion, and every name that is named, not only in this age but in that which is to come” (Ephesians 1:20-21).
Jesus asked God for life, and God gave it to Him — length of days forever and ever! How great is the glory with which God has delivered Him, and the honor and majesty God has placed upon Him. He is most blessed forever, and exceedingly glad with the presence of God, at the right hand of the Father.
And in Him, so are we.
