Hebrews 12:12-15

So take a new grip with your tired hands and strengthen your weak knees. Mark out a straight path for your feet so that those who are weak and lame will not fall but become strong. 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. 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.
