Psalm 138 is unique in that it is entirely about praising and offering heartfelt thankfulness to God. No blessings, no guidance, no solutions to life’s problems are offered up in this hymn to God— just unconditional thankfulness.
The Psalms speak faith in times of disappointment & distress. These are songs of lament we need to sing even though they can be edgy, earthy songs of soul.
Psalms express our spiritual longing, our deep desire to know God and be known by God. How we can identify & address our spiritual longing. Finding God’s nearness. More we’re aware/we hunger for it. Steps know/meet God.
