Matthew 10:36

And a man's foes shall be they of his own household.

The same thought as in verse 21. Peace on earth was promised at the birth of Jesus, Luke 2:14. And peace on earth was earned by the Redeemer, Isaiah 53:5; Romans 5:1; 2 Corinthians 5:18. But here is where the Lord refers to the second, terrible effect of Gospel-preaching, in the case of those that persistently refuse to accept the redemption through the blood of Jesus, 2 Corinthians 2:16. Christ foresaw this hostile opposition to His message; He knew, also, that the spiritual conflict which would be brought on by carnal enmity would find its expression in actual physical persecution. His disciples should not then imagine, as they were likely to do, that there would now be a reign of earthly quietness and peace, with all the blessings which the word implies. Division, contention, war, sudden, fierce calamities would follow the introduction of the Gospel. There is no more bitter hatred and strife than that due to religious differences. It estranges the closest of friends, it disrupts families, it causes lasting enmity between members of the same household. These features will accompany the propagation of the new religion. To stand firm on the side of Christ demands the utmost fearlessness.
