“He prunes every branch that bears fruit.” – John 15:2 NET

“For he will be like a refiner’s fire, like a launderer’s soap. He will act like a refiner and purifier of silver and will cleanse the Levites and refine them like gold and silver. Then they will offer the Lord a proper offering.”

Not only this, but we also rejoice in sufferings, knowing that suffering produces endurance, and endurance, character, and character, hope. And hope does not disappoint, because the love of God has been poured out in our hearts through the Holy Spirit who was given to us.—Endure your suffering as discipline; God is treating you as sons. For what son is there that a father does not discipline? But if you do not experience discipline, something all sons have shared in, then you are illegitimate and are not sons. Now all discipline seems painful at the time, not joyful. But later it produces the fruit of peace and righteousness for those trained by it. Therefore, strengthen your listless hands and your weak knees.
