How do we know that salvation is for all believers?

Scripture consistently affirms that the promise of salvation is extended to all who believe in Christ. For instance, Romans 10:13 states, 'For everyone who calls on the name of the Lord will be saved.' This inclusivity emphasizes that God's plan for redemption encompasses both Jews and Gentiles, aligning with the promise made to Abraham that he would be the father of many nations (Genesis 17:5). As demonstrated in Acts 2:39, the promise is for 'all whom the Lord our God will call', meaning God's elect from every background are included in His salvific purpose.
