“This short hymn of praise celebrates the way in which the great and majestic God who rules over all takes notice of the lowly. Such a God is indeed worthy to be praised by all mankind.” (ESV Study Bible)
This psalm is short, but powerful in encouragement. It presents God as majestic and yet near; transcendent and yet immanent. It is a call to praise Yahweh, who, though enthroned in majesty in heaven, condescends to care for the weak and lowly on the earth.
