The Sole Source of Strength

To the choirmaster. A Psalm of David.

1 O Lord, in your strength the king rejoices,
    and in your salvation how greatly he exults!
2 You have given him his heart's desire
    and have not withheld the request of his lips. Selah
3 For you meet him with rich blessings;
    you set a crown of fine gold upon his head.
4 He asked life of you; you gave it to him,
    length of days forever and ever.
5 His glory is great through your salvation;
    splendor and majesty you bestow on him.
6 For you make him most blessed forever;
    you make him glad with the joy of your presence.
7 For the king trusts in the Lord,
    and through the steadfast love of the Most High he shall not be moved.

8 Your hand will find out all your enemies;
    your right hand will find out those who hate you.
9 You will make them as a blazing oven
    when you appear.
The Lord will swallow them up in his wrath,
    and fire will consume them.
10 You will destroy their descendants from the earth,
    and their offspring from among the children of man.
11 Though they plan evil against you,
    though they devise mischief, they will not succeed.
12 For you will put them to flight;
    you will aim at their faces with your bows.

13 Be exalted, O Lord, in your strength!
    We will sing and praise your power.  – Psalm 21:1-13 ESV

In this Psalm, David, as the Lord’s anointed king, recognizes that any victory or success he enjoys is attributable to God alone. David can’t take any credit for any of it. He has no right to brag or boast about his own strength or military capabilities. His army isn’t the source of his strength. His prowess as a military commander couldn’t explain his record of success. For David, it all pointed back to God.

He boldly proclaims, “The king rejoices in your strength, O LORD!” (Psalm 21:1 NLT), and the joy of victory was due to the gracious intervention of God Almighty. David could look back over his life and see God’s handiwork. His power and presence were evident. His answers to David’s prayers for assistance were too many to count.

For you have given him his heart’s desire;
    you have withheld nothing he requested. – Psalm 21:2 NLT

David is not only grateful, he is blown away by God’s goodness. He has been the undeserving beneficiary of God’s gracious mercy and love. As king, David enjoyed great power, prestige, and prosperity. He had lived a long and productive life, been bestowed with honor, and clothed with splendor and majesty.

But David considered his relationship with God more significant than all the perks that came with his position. The very presence of God meant more to him than anything else. His wealth, fame, and victories were nothing compared to his undeserved privilege of knowing God. In the Book of Jeremiah, Yahweh declares the unsurpassed value of knowing Him.

“Don’t let the wise boast in their wisdom,
    or the powerful boast in their power,
    or the rich boast in their riches.
But those who wish to boast
    should boast in this alone:
that they truly know me and understand that I am the Lord
    who demonstrates unfailing love
    and who brings justice and righteousness to the earth,
and that I delight in these things.” – Jeremiah 9:23-24 NLT

In his letter to the church in Philippi, the apostle Paul wrote of his past accomplishments and defended his right to boast about all he had done.

I could have confidence in my own effort if anyone could. Indeed, if others have reason for confidence in their own efforts, I have even more! – Philippians 3:4 NLT

But instead, Paul stated that he “put no confidence in human effort” (Philippians 3:3 NLT). He recognized that his past achievements were of little value apart from his relationship with Jesus Christ.

I once thought these things were valuable, but now I consider them worthless because of what Christ has done. Yes, everything else is worthless when compared with the infinite value of knowing Christ Jesus my Lord. For his sake I have discarded everything else, counting it all as garbage, so that I could gain Christ and become one with him. – Philippians 3:7-9 NLT

As David wrote Psalm 21, he knew his current successes would not last. His enemies were many, and the likelihood of future conflicts was high. Even his relationship with God couldn’t immunize him from trouble or trials. But he knew he could count on God to hear his prayers and respond. He was confident in God’s unwavering support of His children and sovereign control over the future.

You will capture all your enemies.
    Your strong right hand will seize all who hate you.
You will throw them in a flaming furnace
    when you appear.
The Lord will consume them in his anger;
    fire will devour them.
You will wipe their children from the face of the earth;
    they will never have descendants.
Although they plot against you,
    their evil schemes will never succeed. – Psalm 21:8-11 NLT

David wasn’t immune from trouble. He didn’t live a charmed life free from conflict or potential death. But he knew that God reigned supreme and would ultimately sort out the affairs of men and mete out justice. David rested in the knowledge that the righteous would be rewarded and the wicked would be condemned — all according to God’s wise and just plan.

In this Psalm, David displays a perspective missing among many God-followers today. He expresses a confidence in God that is rare these days. His humility is refreshing but also convicting because we love to take credit for our victories and boast about our own capabilities. Even as Christians, we too often puff out our chests and bask in our own glory. But David reminds us that all glory belongs to God. He looked back over his life and recognized the hand of God in all that he had accomplished as king. Yes, he went into battle, wielded his sword, suffered wounds at the hands of his enemies, killed his fair share of them, and came back tired and bloody. But he recognized the reality that God was the one who brought about victory.

The book of 2 Chronicles contains the story of the people of God facing tremendous odds against a far superior army. Jehoshaphat, the king of Judah, stood before the people and called out to God, confessing their weakness and calling on God to save them. He prayed, “You alone are the God who is in heaven. You are ruler of all the kingdoms of the earth. You are powerful and mighty; no one can stand against you!” (2 Chronicles 20:6 NLT).

He went on to describe their dire circumstances to God and then called out, “O our God, won’t you stop them? We are powerless against this mighty army that is about to attack us. We do not know what to do, but we are looking to you for help” (2 Chronicles 20:12 NLT). As they stood there waiting, the Spirit of God came upon a man named Jahaziel. Under the inspiration of the Spirit, Jahaziel told the people, “This is what the LORD says: Do not be afraid! Don’t be discouraged by this mighty army, for the battle is not yours, but God’s” (2 Chronicles 20:15 NLT).

How did David know this same truth long before Jehoshaphat ever ascended to the throne of Judah? How could he be confident that victory was up to God and not man? Long before David became king of Israel, he experienced first-hand the triumph of God over a far superior enemy of his own. As a young man, he had come face to face with Goliath, a giant of a man who had ridiculed and taunted the men of Israel for days, challenging them to send out a champion to face him. There were no takers — until David appeared on the scene. While every other Israelite soldier, including King Saul, cowered in the shadows, afraid to face their enemy in their own strength, David called out to the boasting Philistine blowhard:

“You come to me with sword, spear, and javelin, but I come to you in the name of the LORD of Heaven’s Armies — the God of the armies of Israel, whom you have defied. Today the LORD will conquer you, and I will kill you and cut off your head. And then I will give the dead bodies of your men to the birds and wild animals, and the whole world will know that there is a God in Israel! And everyone assembled here will know that the LORD rescues his people, but not with sword and spear. This is the LORD’s battle, and he will give you to us!” (1 Samuel 17:45-47 NLT).

Notice what David said: “The Lord will conquer you, and I will kill you.”

Ultimately, he knew this confrontation would be up to God. David had a role to play, but any success would be solely attributable to the LORD. What a valuable lesson for us to learn today as we encounter enemies in our lives. The battle is STILL the Lord’s. Like David, we must learn to trust God and recognize that His unfailing love for us is what keeps us from stumbling in defeat. He is our champion, our strength, and our victory. If we really believe that to be true, then, with David, we can shout, “Rise up, O Lord, in all your power. With music and singing, we celebrate your mighty acts” (Psalm 21:13 NLT).

Father, the battle has always been Yours. Forgive me for sometimes assuming that I bring something of value to the fight. I can do nothing without You. Victory is possible only through You. Continue to teach me to trust in You and to rest in the power You alone can provide. Amen
