Beautiful Feet Share The Gospel.
And how shall they preach unless they are sent? As it is written: “How beautiful are the feet of those who preach the gospel of peace, Who bring glad tidings of good things!” Romans 10:15 NKJV
How welcome the gospel ought to be to those to whom it was preached, because it showed the way to salvation. For this he quotes Isaiah 52:7. The like passage we have, Nahum 1:15, which, if it point at the glad tidings of the deliverance of Israel out of Babylon in the type, yet looks further to the gospel, the good news of our salvation by Jesus Christ.
Observe, What the gospel is: It is the gospel of peace; it is the word of reconciliation between God and man. On earth peace, Luke 2:14. Or, peace is put in general for all good; so it is explained here; it is glad tidings of good things. The things of the gospel are good things indeed, the best things; tidings concerning them are the most joyful tidings, the best news that ever came from heaven to earth.
What the work of ministers is: To preach this gospel, to bring these glad tidings; to evangelize peace (so the original is), to evangelize good things. Every good preacher is in this sense an evangelist: he is not only a messenger to carry the news, but an ambassador to treat; and the first gospel preachers were angels, Luke 2:13.
How acceptable they should therefore be to the children of men for their work's sake: How beautiful are the feet, that is, how welcome are they! Mary Magdalene expressed her love to Christ by kissing his feet, and afterwards by holding him by the feet, Matthew 28:9. And, when Christ was sending forth his disciples, he washed their feet. Those that preach the gospel of peace should see to it that their feet (their life and conversation) be beautiful: the holiness of ministers' lives is the beauty of their feet. How beautiful! namely, in the eyes of those that hear them. Those that welcome the message cannot but love the messengers. See 1 Thessalonians 5:12,13. - Matthew Henry
