Who do you call to be saved?

Romans 10:9-13 NWT

For if you publicly declare with your mouth that Jesus is Lord, and exercise faith in your heart that God raised him up from the dead, you will be saved.

For the scripture says: ‘No one who rests his faith on him will be disappointed.’ For there is no distinction between Jew and Greek. There is the same Lord over all, who is rich toward all those calling on him. For ‘everyone who calls on the name of Jehovah will be saved.’
