While we are supposed to behave in attitude and action that is consistent with his life and teaching, we are also supposed to acknowledge that Jesus is Lord and that He is the one way to the Father.   It is not by works that we get into heaven.  Also, Jesus is not a 'get out of jail free card'.   While some believe that 144,000 will qualify, that is a misreading.   I do not know how many souls will be taken to heaven at the rapture.
The truth is available to other religions but they distort it so that it is no longer recognizable as truth.  Much as this article does.
As far as judging myself, I do that constantly.   I remember the prophecy of the goats and the sheep.
