10 For our earthly fathers disciplined us for a few years, doing the best they knew how. But God’s discipline is always good for us, so that we might share in his holiness. 11 No discipline is enjoyable while it is happening—it’s painful! But afterward there will be a peaceful harvest of right living for those who are trained in this way.
14 Work at living in peace with everyone, and work at living a holy life, for those who are not holy will not see the Lord. 15 Look after each other so that none of you fails to receive the grace of God. Watch out that no poisonous root of bitterness grows up to trouble you, corrupting many.
