32 "And it will come about that whoever calls on the name of the Lord
Will be delivered;
For on Mount Zion and in Jerusalem
There will be those who escape,
As the Lord has said,
Even among the survivors whom the Lord calls.
Once again we see Paul quote another OT passage about YHWH and apply it to Jesus who is the one and only Lord according to the N.T.
that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; 10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation. 11 For the Scripture says, "WHOEVER BELIEVES IN HIM WILL NOT BE DISAPPOINTED." 12 For there is no distinction between Jew and Greek; for the same Lord is Lord of C all, abounding in riches for all who call on Him; 13 for "WHOEVER WILL CALL ON THE NAME OF THE LORD WILL BE SAVED."
