My views are similar to
@Wansvic's but not exactly the same. I believe that baptism has the power to save but that salvation may be possible apart from it; but I think that
@Wansvic takes the hard line and says that one can only be saved by being baptized in Jesus' Name.
Cornelius was an exception to the rule; the rule being found in Acts 2:38-39; in which case repentance, belief, and baptism come before receiving the Holy Ghost.
