I'm afraid that isn't possible. You must understand that any effort... including faith... is an effort on our part is obedience to the law [by the letter or by conscience; and the Bible says that neither one, saves (Romans 2:14-24 & 3:19-20)].
19 Now we know that what things soever the law saith, it saith to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.
20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
Romans 3:19-20
