Psalm 28:7 (NKJV)
7 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.
In our continuing study of Jesus in the Psalms we examine Psalm 28 today. Verse 7 of Psalm 28 reminds us how central worship ought to be to our experience as the people of God. As we will see, God has answered David’s cry for help. So what does David do? He composes a song to celebrate the Lord’s goodness.
Since we have been doing a series of meditations on worship, I want to use this time to consider David’s song of praise in Psalm 28. David tells us that his heart trusted in the Lord – he believed that God would be true to His word and deliver him from trouble. And what happened? God answered him. My heart trusted in Him, and I am helped. You can imagine, therefore, how thankful David was. Any time our desires are fulfilled, it is natural to be filled with joy. Our team wins the game – we are joyful. We receive the present we had desired – we are joyful. We recover from illness – we are joyful. And David’s response was no different. Therefore my heart greatly rejoices. His heart was filled with joy because God had mercifully answered his plea.
But note that David’s internal joy manifest itself externally; his heart of joy bore fruit in song. Therefore my heart greatly rejoices, and with my song I will praise Him. God saved David; consequently, David’s heart was filled with joy; and David’s joy bore fruit in praise and song. His joyful heart opened his mouth. As John Calvin wrote, “undoubtedly, when God spreads cheerfulness through our hearts, it is to open our mouths to sing his praises” (Psalms, 472). God gives us joy so that we might worship.
So what do you do when your heart is joyful? Do you direct the joy that is in Your heart in praise to God? James, the brother of our Lord, asks us, “Is anyone cheerful? Let him sing psalms” (James 5:13b). James exhorts us: Don’t waste your joy! There are plenty of times when our heart will be weighed down and sorrowful; times for prayer and petition. But if your heart is joyful, then let it bear fruit in song – and not just in song, in songs of praise to God.
So what of you? Have you sung the praises of God? Have you spoken the wonders of God? Have you shared the rich treasures of God with others? Or have you wasted your joy?

Reminded that we often waste our joy, let us confess our sin to the Lord, seeking His forgiveness. We will have a time of silent confession, followed by the corporate confession found in your bulletin. As you are able, let us kneel together as we confess.
