Read Psalm 21
God – The Source of Strength
David was the king over all Israel, yet even with all the power and might he possessed, he recognized there was One even more powerful. “The king shall have joy in Your strength, O Lord; and in Your salvation how greatly shall he rejoice!” (Psalm 21:1).
Notice the gratitude of the king toward God in this Psalm. He is thankful that God has not only heard but granted his requests. “You have given him his heart’s desire, and have not withheld the request of his lips” (Psalm 21:2).
He recognizes that God is the source of “blessings of goodness”; it was God who even “set a crown of pure gold upon (the king’s) head)” (Psalm 21:3). God would lengthen the king’s rule and provide salvation, honor, and majesty to the throne (Psalm 21:4-5).
God’s blessings created steadfast joy in the heart of the king, knowing that He would guard and protect His faithful followers and execute justice upon those who oppose Him and His people. “For the king trusts in the Lord, and through the mercy of the Most High he shall not be moved. Your hand will find all Your enemies; Your right hand will find those who hate You” (Psalm 21:7-8).
Those who set out to oppose God will not succeed. He “shall swallow them up in His wrath” (Psalm 21:9). “They devised a plot which they are not able to perform” (Psalm 21:11).
No man’s strength can ever overtake the Almighty; He is the One who provides strength to men. “Be exalted, O Lord, in Your own strength! We will sing and praise Your power” (Psalm 21:13).
Do we not serve the same Almighty God today that David served while he sat on the throne? Our wildest imaginations cannot match the power, the strength, or the blessings that are available to the children of God. “Now to Him who is able to do exceedingly abundantly above all that we ask or think, according to the power that works in us, to Him be glory in the church by Christ Jesus to all generations, forever and ever. Amen” (Ephesians 3:20-21).
