Romans 10:9,10,13And the Lord one must confess to be saved as per Joel 2:32 is YHWH. Paul says Jesus is YHWH of Joel 2:32 that must be confessed to be saved.
because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes and is justified, and with the mouth one confesses and is saved. For the Scripture says, “Everyone who believes in him will not be put to shame.” For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. For “everyone who calls on the name of the Lord will be saved.”
In this context Jesus is Lord. Nothing else needs to be said . . . thanks.
