Romans 10:13

for, Whosoever shall call upon the name of the Lord shall be saved.

'For' -again, O.T. scripture (Joel 2) is cited as proof that this doctrine isn't new. The very Scriptures that the Jewish people possessed taught this truth. Who will be saved? The man who merits salvation? No-'call' The Jew only? No-'whosoever'.

'call' -And what does this imply? 'Their inability to save themselves. This is the cry of someone in NEED. To call upon his name is to beg him for aid and salvation.' (McGuiggan p. 311)

Note: Peter quoted this same Scripture on the day of Pentecost (Acts 2). But what were the people told to do on that day in order to be 'saved'? Repent and be baptized (Acts 2). The same was truth is found in the example of Paul's own conversion (Acts 22:16 '..Arise, and be baptized, and wash away your sins, calling on His name '). Therefore, one hasn't truly depended on God for salvation, until they have submitted to His command to be baptized. (Mark 16:16)

'name of the Lord' -in the passage quoted (Joel 2:32), the 'Lord' under consideration is Jehovah (ASV). One more Scripture that includes Jesus of the N.T., in the name 'Jehovah' in the O.T.
