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.
“WHOEVER WILL CALL ON THE NAME OF THE LORD WILL BE SAVED." (Romans 10:13)
“so that at the name of Jesus EVERY KNEE WILL BOW, of those who are in heaven and on earth and under the earth, and that every tongue will confess that Jesus Christ is Lord, to the glory of God the Father” (Philippians 2:10-11)
