"Every day with Jesus is not sweeter than the day before. We know it from experience and we know it from Scripture. For David says in Psalm 19:7, “The law of the LORD is perfect, reviving the soul.” If every day with Jesus were sweeter than the day before, if life were a steady ascent with no dips in our affection for God, we wouldn’t need to be re-vived."
John Piper, Desiring God
