Will anyone in heaven be able to brag about how they got there?
No. Salvation is by grace through faith, not of works, so no one in glory can claim credit. Every believer, Old Testament as well as us, is there by faith plus nothing; it is God's gift, not human achievement, leaving no room for eternal bragging.
Les explains that grace has made salvation possible, but faith is the vehicle. It is not of yourselves; it is the gift of God, not of works. If works could save, people would brag all over heaven for all eternity, and others would cross over to avoid hearing it again. But that will not be the case: not a single soul in glory will be able to brag about what they did to get there, because every person, Old Testament as well as us, is there by faith plus nothing. Salvation does not stop there; believers are also His workmanship, a recreation of God Himself.
