“And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!”
King James Version (KJV)
10:15 But how shall they preach, unless they be sent - Thus by a chain of reasoning, from God's will that the gentiles also should call upon him, St. Paul infers that the apostles were sent by God to preach to the gentiles also. The feet - Their very footsteps; their coming. #Isa 52:7|.
Ro 10:15 And how shall they preach, except they be sent? Those must go out to them who have knowledge of the gospel. Hence it was needful that the apostles and evangelists be "sent". Hence Christ said, "Go into all the world and preach to every creature" (Mr 16:15 Mt 28:19). Thus Paul shows the duty was laid upon him to preach to Greek as well as Jew. As it is written. See Isa 52:7. How beautiful are the feet of them that preach the gospel, etc. This message was to the Gentiles blessed tidings, and the passage quoted from Isaiah shows, under a figure, how those would rejoice who believed the glad news. See Ac 13:38.
