John Piper, in a sermon, “There is Salvation in No One Else”
Peter pushed the universality of Jesus from the no-count town of Nazareth as far as it could be pushed. Jesus is absolutely unique. He is absolutely supreme among all the gods and lords of the world religions. Knowing him and believing on his name is absolutely necessary for salvation. For since the cross and resurrection there is no other way to God and to heaven. Therefore, as Paul says in Acts 17:30–31,
God commands all men everywhere to repent, because he has fixed a day on which he will judge the world in righteousness by a man whom he has appointed, and of this he has given assurance to all men by raising him from the dead.
This is a fundamental biblical fact that we have to come to terms with if we aim to be biblical Christians in a pluralistic nation and a pluralistic world. It’s the kind of truth that either makes converts or makes enemies. It is not a live-and-let-live truth.
