It is just as the Scripture says: “Anyone who believes in Him will never be put to shame.” For there is no difference between Jew and Greek: The same Lord is Lord of all, and gives richly to all who call on Him, for, “Everyone who calls on the name of the Lord will be saved.” How then can they call on the One in whom they have not believed? And how can they believe in the One of whom they have not heard? And how can they hear without someone to preach? And how can they preach unless they are sent? As it is written: “How beautiful are the feet of those who bring good news!” (Romans 10:11-15)
A reasonable reply to those who assert that the date of Jesus’ return is fixed, I suggest, is to inquire whether that belief retards their effort in obeying their Lord’s Great Commission.
