In Psalm 103 we see David repeatedly using the phrase “bless the Lord, O my soul”. To “bless the Lord” was to “praise the Lord”. So, David was exhorting himself to praise God. He was trying to stir up in himself praise and adoration for God.
And the way David motivated himself to praise God was to remind himself of who God was and what God had done for Him. He writes, “Bless the Lord, O my soul, and forget not all his benefits” (v.2). There is a real correlation between blessing God and remembering all His benefits (provision, mercy, sovereignty, etc.).
So often the reason we are not satisfied in God and therefore do not praise Him as we should is because we forget all His benefits. That’s why David proclaims, “Let my soul not forget the benefits of God” because when we forget all that God has done, we don’t rejoice in Him as we should.
When it comes to God, forgetfulness equals joylessness. And we are a forgetful people. We forget to turn the lights off, take the trash out, pay the electric bill, etc. These are things that we forget. And so often when we forget there are consequences. Some are small and insignificant, others are big and costly, but there are often consequences to our forgetfulness. And when it comes to God the consequence of forgetfulness is joylessness. When we are not reminded of who God is and what God has done for us then it’s easy to become discontent and depressed in life. The joy of the Lord is missing because we’re not dwelling on Him.
David stirs himself up to praise and adoration for God by reminding himself of the benefits of God.
We too need to regularly remind ourselves of who God is and what He has done for us. It is crucial in the pursuit of joy that we regularly read God’s Word, listen to Biblical preaching, and have godly mentors in our lives to remind us again and again of the benefits we have in Christ.
