Is there any other name by which a person can be saved?
No. Scripture declares an exclusivist gospel: there is no other name given among men whereby we must be saved than the name of Jesus. The way is narrow, but it is available to anyone who will simply believe it. Apart from Jesus, there is no salvation.
Les teaches that the gospel is exclusivist because that is what the book declares. He points out that there is no other name given among men whereby we must be saved than the name of Jesus, and that is where salvation is found. He acknowledges that many are going to an eternal devil's hell because they will not come into this exclusivist narrow way that God has prescribed. People may object that God is unfair, but Les says the problem is that God is too fair. He has made the way narrow, yet the way in is so easy that anybody can find it if they simply believe. Les uses John's Gospel, Chapter 10, and the analogy of the sheepfold and the door: anyone who enters the sheepfold must come in by the door; if he tries to come in over the top, he is a thief and a robber.
Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
