Hebrews 12:11-13 (NLT)
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.
12 So take a new grip with your tired hands and strengthen your weak knees. 13 Mark out a straight path for your feet so that those who are weak and lame will not fall but become strong.
