God is actively engaged in preserving knowledge — the body of truth and wisdom He has revealed. He is equally active in overthrowing the words of those who sin and distort truth. This is a profound assurance: truth does not need our defence as much as it needs our faithfulness — God himself guards it.
Memory phrase: God guards truth always.
Talk about it: What does it mean that God watches over truth?
Prayer: God, thank You for protecting what is true.
