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. 14 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. 15 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. 16 Make sure that no one is immoral or godless like Esau, who traded his birthright as the firstborn son for a single meal. 17 You know that afterward, when he wanted his father's blessing, he was rejected. It was too late for repentance, even though he begged with bitter tears.

Commentary on Hebrews 12:12-17
(Read Hebrews 12:12-17)
A burden of affliction is apt to make the Christian's hands hang down, and his knees grow feeble, to dispirit him and discourage him; but against this he must strive, that he may better run his spiritual race and course. Faith and patience enable believers to follow peace and holiness, as a man follows his calling constantly, diligently, and with pleasure. Peace with men, of all sects and parties, will be favourable to our pursuit of holiness. But peace and holiness go together; there can be not right peace without holiness. Where persons fail of having the true grace of God, corruption will prevail and break forth; beware lest any unmortified lust in the heart, which seems to be dead, should spring up, to trouble and disturb the whole body. Falling away from Christ is the fruit of preferring the delights of the flesh, to the blessing of God, and the heavenly inheritance, as Esau did. But sinners will not always have such mean thoughts of the Divine blessing and inheritance as they now have. It agrees with the profane man's disposition, to desire the blessing, yet to despise the means whereby the blessing is to be gained. But God will neither sever the means from the blessing, nor join the blessing with the satisfying of man's lusts. God's mercy and blessing were never sought carefully and not obtained.
