Such is your own personal interpretation of Scripture.
Mark 16:16 Luke 7:50. Seems that - as far as Jesus was concerned - faith alone can save a person.
And in Acts 16:30-31 we see that Paul and Silas confirm that faith alone is sufficient to be saved.
"16 "For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. 17 For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. 18 Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God."
Galatians 1:
"9 As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed."
