Kings have everything. If you were a King, what would you rejoice in the most? In what did David rejoice? Psalm 21 tells us what it means to be a king - not for a day but for a lifetime.
We are kings because we are God's children. Jesus Christ has made us kings and priests because He love us and washed away our sins in His blood. Today, God wants us to reign in life. We are on the throne with the Lord Jesus. "The king shall have joy in Your strength, O Lord" (v. 1). David is rejoicing in the strength that God gave him - strength to walk and strength to war; strength to build and strength to battle, strength to carry the burdens of life. Are you rejoicing today as God's king because He gives you strength?
David continues, "And in Your salvation how greatly shall he rejoice!" He rejoices in God's salvation. We need to do the same. One day Jesus told His disciples, "Don't rejoice because the demons are subject to you. Rejoice because your names are written down in heaven" (see Luke 10:20).
David also rejoices in satisfaction. "You have given him his heart's desire, and have not withheld the request of his lips. For You meet him with the blessings of goodness" (vv. 2-3). If we look back, we will find goodness and mercy following us, and if we look ahead, God is meeting us with His goodness (v. 3). Don't be afraid of today, and don't be afraid of the future. God will meet you with His goodness.
In verse 7 David rejoices in stability: "For the king trusts in the Lord, and through the mercy of the Most High he shall not be moved." I like these blessings we can rejoice in - God's strength, salvation, satisfaction, and stability. All of this is for God's glory. "His glory is great in Your salvation" (v. 5).
Many Christians fail to see themselves as kings. But God wants us to reign in life and has provided several blessings that enable us to live as kings. Are you enjoying the blessings of kingship? If not, claim His blessings and start living a life of victory.
