Does this really mean what the plain text seems to say?

Christianity is often portrayed as exclusionary.  Here is one of the texts that are used to show that Christianity is exclusionary.

John 14:6(NKJV)

Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father except through Me.

Jesus is clearly saying that no one comes to the Father (God) except through Jesus.  Many say that is exclusionary.  Many think that you should be able to get into Heaven whether you believe in Jesus or not.  I would disagree.

God is the creator of Heaven and Earth.  It's His thing.  He gets to set the rules.  So let's look at the rules He set.  As far as getting into Heaven, there is basically one requirement.  Faith in Jesus. 

All of those who believe in Jesus get in to Heaven.  No exceptions.  So if everyone on earth can get into Heaven whether God wants them there or not, just by believing in Jesus, is it really exclusionary?
