Two systems making contradictory claims to absolute truth can't possibly both be correct. Either one, the other, or neither is correct. If Jesus' says he is the way the truth and the life and no one will see the father except through him and all other religions propose different versions of the same old man made standard of working your way to heaven idea, then both Christianity and all the rest can't be correct. If Christianity is true they are false and vice versa. I do not think a benevolent God God would hide his word in all kinds of books making contradictory claims.
Jesus will at the right hand of the Father as Judge/Gatekeeper. You have to get through the gate keeper in order to get into the Kingdom.
What Jesus is judging is works as stated clearly in numerous passages.
"faith alone/ without works" is then a contradiction of what Jesus says is a requirement for entrance into heaven.
James 2 points out this contradiction and addresses it through the whole Chapter stating "Faith without works is DEAD" which he repeats 3 times in case some did not get it on the first round.
To think that you can go around raping, killing, and doing all kinds of other horrible things and then just show up and Claim "I have faith" will do you little good according to Jesus. Not only that but "faith alone" makes absolutly no sense from a rational perspective.
Proverbs does not say "seek stupitidy" .. it says seek knowledge.
This includes figuring out that parts of the Bible are nonsense written by man based on the whim of the editor rather than the authentic teachings of Jesus.
