Luke 10:6

And if the son of peace be there,....

(1.) The charge given them was, Whatsoever house they entered into, they must say, Peace be to this house. Here, [1.] They are supposed to enter into private houses; for, being not admitted into the synagogues, they were forced to preach where they could have liberty. And, as their public preaching was driven into houses, so thither they carried it.

The son of peace - In the Jewish style, a man who has any good or bad quality is called the son of it. Thus, wise men are called the children of wisdom, Mat 11:19; Luk 7:35. So, likewise, what a man is doomed to, he is called the son of, as in Eph 2:3, wicked men are styled the children of wrath: so Judas is called the son of perdition, Joh 17:12; and a man who deserves to die is called, 2Sa 12:5, a son of death.

The verses before us relate a circumstance which is not recorded by any Gospel writer except Luke. That circumstance is our Lord's appointment of seventy disciples to go before Him, in addition to the twelve apostles. We do not know the names of any of these disciples. Their subsequent history has not been revealed to us. But the instructions with which they are sent forth are deeply interesting, and deserve the close attention of all ministers and teachers of the Gospel. The first point in our Lord's charge to the seventy disciples — is the importance of prayer and intercession.

But the instructions with which they are sent forth are deeply interesting, and deserve the close attention of all ministers and teachers of the Gospel. The first point in our Lord's charge to the seventy disciples — is the importance of prayer and intercession. This is the leading thought with which our Lord opens His address. Before He tells His ambassadors what to do, He first bids them to pray, "Pray to the the Lord of the harvest, that He would send forth laborers into his harvest." Prayer is one of the best and most powerful means of helping forward the cause of Christ in the world! It is a means within the reach of all who have the Spirit of adoption. Not all believers have money to give to missions. Very few have great intellectual gifts, or extensive influence among men. But all believers can pray for the success of the Gospel — and they ought to pray for it daily. Many and marvelous are the answers to prayer which are recorded for our learning in the Bible. "The fervent prayer of a righteous man avails much." (James 5:16.) Prayer is one of the principal weapons which the minister of the Gospel ought to use. To be a true successor of the apostles, he must give himself to prayer — as well as to the ministry of the word. (Acts 6:4.) He must not only use the sword of the Spirit, but pray always, with all prayer and supplication. (Ephesians 6:17,18.) This is the way to win a blessing on his own ministry. This, above all, is the way to procure helpers to carry on Christ's work. Colleges may educate men.

The son of peace - That is, if the “house” or “family” be “worthy,” or be disposed to receive you in “peace” and kindness. See Mat 10:13. “The son of peace” means one “disposed” to peace, or peaceful and kind in his disposition. Compare Mat 1:1.
