What you say is false and rather dumb, really.
You allow that any conviction is ultimately wrong but all 'flaws' are right and true.
I ask you, Does one ever attain to Truth ? If you say 'no' then you have no argument. And if you say 'yes' it is all on you to show it.
Jesus is the Promised One, the Son of God. Do I understand all that He said ? No. But that is irrelevant. He Himself even said so.
