I don't get the negativity. It has to be possible, or the Bible and Christ are a lie.
People who say that Jesus can't or won't save someone else are doing themselves the ultimate wrong. Denying that his saving grace works for others means it won't won't for those who say He is wrong.
People have to cooperate, obviously, but the grace of Jesus is there for anyone who asks and accepts.
Agreed. The gospel IS “the power of God unto salvation to every one that believeth...”—Romans 1:16
