Here is another simple syllogism (i.e., the third of three), using biblical evidence, to support the notion that all will be saved.
Premise 1: All who call on the name of the Lord will be saved. (Romans 10:13)
Premise 2: All will call on the name of the Lord. (Philippians 2:10-11)
Conclusion: All will be saved.
A major assumption in this argument is confessing that Jesus is Lord (from Philippians 2:10-11) is a sufficient condition of calling on the name of the Lord (from Romans10:13). That is, in this argument, it is assumed that one cannot confess that Jesus is Lord without also calling on the name of the Lord.
