Psalm 90 outlines timely principles for living with an eternal God. It begins by establishing that God has been a dwelling place for generations and existed before creation. Then it notes that humans lives are short like grass compared to God's eternity. Finally, it prescribes principles like acknowledging God as creator and sovereign, living wisely in light of our brevity, and finding satisfaction in God. The overall message is that understanding God's eternal nature should constantly influence how we live.
