11. 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].
12. 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.]
13. And cut through and make firm and plain and smooth, straight paths for your feet [yes, make them safe and upright and happy paths that go in the right direction], so that the lame and halting [limbs] may not be put out of joint, but rather may be cured.
14. Strive to live in peace with everybody and pursue that consecration and holiness without which no one will [ever] see the Lord.
15. Exercise foresight and be on the watch to look [after one another], to see that no one falls back from and fails to secure God's grace (His unmerited favor and spiritual blessing), in order that no root of resentment (rancor, bitterness, or hatred) shoots forth and causes trouble and bitter torment, and the many become contaminated and defiled by it–
16. That no one may become guilty of sexual vice, or become a profane (godless and sacrilegious) person as Esau did, who sold his own birthright for a single meal. [Gen. 25:29-34.]
17. For you understand that later on, when he wanted [to regain title to] his inheritance of the blessing, he was rejected (disqualified and set aside), for he could find no opportunity to repair by repentance [what he had done, no chance to recall the choice he had made], although he sought for it carefully with [bitter] tears. [Gen. 27:30-40.]
18. For you have not come [as did the Israelites in the wilderness] to a [material] mountain that can be touched, [a mountain] that is ablaze with fire, and to gloom and darkness and a raging storm,
19. And to the blast of a trumpet and a voice whose words make the listeners beg that nothing more be said to them. [Exod. 19:12-22; 20:18-21; Deut. 4:11, 12; 5:22-27.]
20. For they could not bear the command that was given: If even a wild animal touches the mountain, it shall be stoned to death. [Exod. 19:12, 13.]
21. In fact, so awful and terrifying was the [phenomenal] sight that Moses said, I am terrified (aghast and trembling with fear). [Deut. 9:19.]
22. But rather, you have come to Mount Zion, even to the city of the living God, the heavenly Jerusalem, and to countless multitudes of angels in festal gathering,
23. And to the church (assembly) of the Firstborn who are registered [as citizens] in heaven, and to the God Who is Judge of all, and to the spirits of the righteous (the redeemed in heaven) who have been made perfect,
24. And to Jesus, the Mediator (Go-between, Agent) of a new covenant, and to the sprinkled blood which speaks [of mercy], a better and nobler and more gracious message than the blood of Abel [which cried out for vengeance]. [Gen. 4:10.]
25. So see to it that you do not reject Him or refuse to listen to and heed Him Who is speaking [to you now]. For if they [the Israelites] did not escape when they refused to listen and heed Him Who warned and divinely instructed them [here] on earth [revealing with heavenly warnings His will], how much less shall we escape if we reject and turn our backs on Him Who cautions and admonishes [us] from heaven?
26. Then [at Mount Sinai] His voice shook the earth, but now He has given a promise: Yet once more I will shake and make tremble not only the earth but also the [starry] heavens. [Hag. 2:6.]
27. Now this expression, Yet once more, indicates the final removal and transformation of all [that can be] shaken–that is, of that which has been created–in order that what cannot be shaken may remain and continue. [Ps. 102:26.]
28. Let us therefore, receiving a kingdom that is firm and stable and cannot be shaken, offer to God pleasing service and acceptable worship, with modesty and pious care and godly fear and awe;
