In this verse God patiently explains to Job the limitations He has set for the waves of the sea. Sometimes we think evil has no bounds— that it has free reign to wreak havoc in our lives without any restrictions. However, God Almighty sets the stopping point for the attacks of the devil against us.
In Job’s life God had a predetermined time when He would suddenly throw the whole process into reverse, thus ending the greatest test endured by any human being other than Christ. Job’s patience in trial became the most significant witness of patience in biblical history: “We give great honor to those who endure under suffering. Job is an example of a man who endured patiently. From his experience we see how the Lord’s plan finally ended in good, for he is full of tenderness and mercy” (James 5:11).
The proud waters of evil may be threatening to overwhelm you, but God knows the moment when they will hit their predetermined limit. On that day your enemy will be like a wild dog at the end of a long chain, and you will be able to rest peacefully as God says to the enemy, “This far and no farther!”
