What does Psalm 33:5 mean?

This verse supplies additional reasons to praise the Lord joyfully with a new song (Psalm 33:1–4). Unlike imaginary pagan gods, the Lord is not fickle or malicious. He acts according to His perfect, unchanging nature, which means He approves of that which is correct and fitting. As the righteous judge, He never condones or excuses sin. He can forgive sin, but He does not excuse it. Nor does He render a false verdict. He is not only righteous and just but also replete in steadfast love. Believers may be certain that His love never weakens or retreats. It is unconditional. His love is universal. David writes that "the earth is full of the steadfast love of the LORD." Creation affirms the Lord's love. He has provided everything human beings need to live abundantly (Psalm 16:11; John 10:10).

In Psalm 145:17 David proclaims: "The LORD is righteous in all his ways and kind in all his works." The apostle Paul also affirms the Lord's righteousness. In 2 Timothy 4:8 he refers to the Lord as "the righteous judge."
