This is a delightful Psalm of happy praise to God. It’s one of David’s, and they think it probably dates from his later years.
It’s a nice counterpoint to yesterday’s, from the start of his reign promising sincerely to stay pure, strong and good.
Older David is still praising unreservedly, but thanking God over and over for lifting the burden of his sin, his failure. It has a wonderful light, spacious feeling.
As high as the heavens is the size of god’s love, as far a the East is from the West has he removed David’s sin.
He remembers god’s patient compassion to past generations and looks forward to an eternal future of god’s rule, erasing the sadness of the ending of our frail ephemeral span of years.
He lists the benefits of being God’s: personally he’s been pulled from the pit, given a crown of love and compassion (more worth mentioning than the earthly crown) provided good things and he feels young and invigorated, ready to soar like an eagle.
It’s just wonderful intimate tumbling praise of a person filled with God’s spirit.
The righteousness and justice phrase describes god’s objective again.
Righteousness and justice; forgiveness and love. Being the beginning and end of all those seemingly irreconcilable things is the mystery and power of our triune God.
But that’s not a heavy thing to think about, it’s light, fizzy and best expressed in a song.
