Our culture is obsessed with temporal things. We want instant gratification. We don’t want to be bothered with the future, much less eternity. However, as David Platt reminds us from Psalm 90, we serve a God who is eternal. His perfections––His justice, His love, His wrath, His faithfulness, His grace––had no beginning, and they will have no end. These biblical realities should help us live for that which truly matters. Sin is more serious than we ever realized, but God’s grace is greater than we ever imagined. Our God is unchanging, and this is good news for those who have trusted in His Son.
