Hebrews 12:14

Follow peace with all men - Cultivate, as far as you possibly can, a good understanding, both with Jews and Gentiles. Ειρηνην διωκετε, pursue peace with the same care, attention, and diligence, as beasts do their game; follow it through all places; trace it through all winding circumstances; and have it with all men, if you can with a safe conscience.

And holiness - Τον ἁγιασμον· That state of continual sanctification, that life of purity and detachment from the world and all its lusts, without which detachment and sanctity no man shall see the Lord - shall never enjoy his presence in the world of blessedness. To see God, in the Hebrew phrase, is to enjoy him; and without holiness of heart and life this is impossible. No soul can be fit for heaven that has not suitable dispositions for the place.

Follow peace with all men - Do not give indulgence to those passions which lead to litigations, strifes, wars; see the notes on Romans 14:19. The connection here requires us to understand this mainly of persecutors. The apostle is referring to the trials which those whom he addressed were experiencing. Those trials seem to have arisen mainly from persecution, and he exhorts them to manifest a spirit of kindness toward all - even though they were engaged in persecuting them. This is the temper of the gospel. We are to make war with sin, but not with people; with bad passions and corrupt desires, but not with our fellow-worms.

And holiness - Instead of yielding to contending passions and to a spirit of war; instead of seeking revenge on your persecutors and foes, make it rather your aim to be holy. Let that be the object of your pursuit; the great purpose of your life. Men might in such cases counsel them to seek revenge; the spirit of religion would counsel them to strive to be holy. In such times they were in great danger of giving indulgence to evil passions, and hence, the special propriety of the exhortation to endeavor to be holy.

Without which no man shall see the Lord - That is, shall see him in peace; or shall so see him as to dwell with him. All will see him in the day of judgment, but to "see" one is often used in the sense of being with one; dwelling with one; enjoying one; see the notes on Matthew 5:8. The principle here stated is one which is never departed from; Revelation 21:27; Isaiah 35:8; Isaiah 52:1; Isaiah 60:21; Joel 3:17; Matthew 13:41; 1 Corinthians 6:9-10. No one has ever been admitted to heaven in his sins; nor is it desirable that anyone ever should be. Desirable as it is that lost people should be happy, yet it is benevolence which excludes the profane, the impious, and the unbelieving from heaven - just as it is benevolence to a family to exclude profligates and seducers, and as it is benevolence to a community to confine thieves and robbers in prison. This great principle in the divine administration will always be adhered to; and hence, they who are expecting to be saved without holiness or religion, are destined to certain disappointment.

Heaven and earth will pass away, but God will not admit one unrepenting and unpardoned sinner to heaven. It was the importance and the certainty of this principle which made the apostle insist on it here with so much earnestness. Amidst all their trials; when exposed to persecution; and when everything might tempt them to the indulgence of feelings which were the opposite of holiness, they were to make it their great object to be like God. For this they were to seek, to strive. to labor, to pray. This with us in all our trials should also be the great aim of life. How deeply affecting then is the inquiry whether we have that holiness which is indispensable to salvation! Let us not deceive ourselves. We may have many things else - many things which are in themselves desirable, but without this one thing we shall never see the Lord in peace. We may have wealth, genius, learning, beauty, accomplishments, houses, lands, books, friends - but without religion they will be all in vain. Never can we see God in peace without a holy heart; never can we be admitted into heaven without that religion which will identify us with the angels around the throne!

12:14 Follow peace with all men - This second branch of the exhortation concerns our neighbours; the third, God. And holiness - The not following after all holiness, is the direct way to fall into sin of every kind.
