Hebrews 12:5-12

And have you [completely] forgotten the divine word of appeal and encouragement in which you are reasoned with and addressed as sons? My son, do not think lightly or scorn to submit to the correction and discipline of the Lord, nor lose courage and give up and faint when you are reproved or corrected by Him; For the Lord corrects and disciplines everyone whom He loves, and He punishes, even scourges, every son whom He accepts and welcomes to His heart and cherishes. You must submit to and endure [correction] for discipline; God is dealing with you as with sons. For what son is there whom his father does not [thus] train and correct and discipline? Now if you are exempt from correction and left without discipline in which all [of God's children] share, then you are illegitimate offspring and not true sons [at all]. [Prov. 3:11, 12.] Moreover, we have had earthly fathers who disciplined us and we yielded [to them] and respected [them for training us]. Shall we not much more cheerfully submit to the Father of spirits and so [truly] live? For [our earthly fathers] disciplined us for only a short period of time and chastised us as seemed proper and good to them; but He disciplines us for our certain good, that we may become sharers in His own holiness. For the time being no discipline brings joy, but seems grievous and painful; but afterwards it yields a peaceable fruit of righteousness to those who have been trained by it [a harvest of fruit which consists in righteousness–in conformity to God's will in purpose, thought, and action, resulting in right living and right standing with God]. So then, brace up and reinvigorate and set right your slackened and weakened and drooping hands and strengthen your feeble and palsied and tottering knees, [Isa. 35:3.]
