Hebrews 12:13

10 For they truly gave us punishment for a short time, as it seemed good to them; but he does it for our profit, so that we may become holy as he is.

11 At the time all punishment seems to be pain and not joy: but after, those who have been trained by it get from it the peace-giving fruit of righteousness.

12 For this cause let the hands which are hanging down be lifted up, and let the feeble knees be made strong,

13 And make straight roads for your feet, so that the feeble may not be turned out of the way, but may be made strong.

14 Let your desire be for peace with all men, and to be made holy, without which no man may see the Lord;

15 Looking with care to see that no man among you in his behaviour comes short of the grace of God; for fear that some bitter root may come up to be a trouble to you, and that some of you may be made unclean by it;

16 And that there may not be any evil liver, or any man without respect for God, like Esau, who let his birthright go for a plate of food.
