“The Lord is my strength and my shield; My heart trusted in Him, and I am helped; Therefore my heart greatly rejoices, And with my song I will praise Him.”
Years ago I injured my knee and required surgery. Before the operation, I was given a detailed description of the human knee. I learned how it was constructed, how it functioned and how mine was damaged. When the surgery was completed, I was even given a video of the operation. If I wanted to, I could have watched on the big screen as parts were cut away and replaced. I learned things I never really wanted to know.
David expresses praise to God for being his strength and his shield. It is important to keep in mind, the only way to know the strength of the Lord is to encounter your own weakness. It was the times when David reached the end of himself that he would come face to face with the reality of the power, strength and enabling of God. All of us want to know God’s power, but we need to realize He only gives it when we are facing things that our own strength cannot handle. Paul prayed to know the power of the resurrection. He needed that because he was constantly in situations where his own power was insufficient. Those who truly know the power of God, are those who have come to realize their own weakness.
The same concept is true regarding a shield. What sounds like beautiful poetic expression, also has a real and practical backstory. David knew God to be his shield because he faced situations in life where he was forced to hide from the attack of others. He had to duck from the spear of Saul, hide in the caves of Adullum, and even flee outside the borders of the land. It was in the times of greatest attack that David learned he could hide himself under the protective shield of His God.
Whatever you are facing, it is good to know that your strength does not have to be sufficient. You can break, and when you do, you can find the strength of the Lord to be enough. No matter what the enemy hurls at you, the shield of the Lord is a fortress that will not fail.
