How does Romans 10:13 differ from Peter's quote of Joel in Acts 2:21?
Peter's quotation of Joel in Acts 2:21 applies under the Old Testament economy, with salvation linked to Israel and Jerusalem. Romans 10:13 repeats the same words, but it is not kingdom ground and is not accomplished through Israel; Paul uses it for the present time, not the kingdom program.
Les explains that Peter had just quoted Joel, so Acts 2:21 says “whosoever shall call on the name of the Lord shall be saved” under the Old Testament economy. In that setting, Peter expected the tribulation and the kingdom, when men would take hold of a Jew and go to Jerusalem because they had heard God was with him there. Paul later writes the identical words in Romans 10:13, but Les stresses that Paul’s use is not kingdom ground and is not done through Israel. Instead, it applies where we are today. In Romans 10:8 Paul says the word is nigh thee, in thy mouth and in thy heart.
For whosoever shall call upon the name of the Lord shall be saved.
