'Before the Lord' can mean either in God's sight (implying awareness) or in defiance of God. Many scholars read this as Nimrod asserting himself against God — using his power for his own agenda, not God's.
Memory phrase: True strength is used in God's service.
Talk about it: Have you ever seen someone use their strength or power in a way that was not honouring to God? What happened?
Prayer: God, help me be strong in a way that honours You — not in a way that pushes You aside.
