A sermon series through Book Four of the Psalms (Psalms 90–106), where God’s people are taught to look beyond earthly kingdoms and changing circumstances to the everlasting reign of the Lord. These Psalms call us to number our days, trust God’s providence, worship Him as King, remember His mighty works, and rest in His covenant faithfulness. In a world marked by frailty, exile, and uncertainty, Book Four directs our hope to the God who reigns forever.
