Are all beliefs the same?

It's popular in our culture to say that all beliefs are equal, that all beliefs are true.  The idea that it doesn't matter what you believe because if you are basically a decent person that's all that matters.  What you believe is like choosing ice cream, I like vanilla and you like strawberry it's just all about preference and neither one of us is wrong.

It's interesting because each belief system doesn't teach that even if they say they do.  Can God exist and not exist at the same time?  Can God be personal and impersonal at the same time?  Can Jesus be the only way to God and not be the only way to God at the same time?  These aren't trick questions.  Something can't be and not be at the same time.  Answering yes is a violation of the law of non-contradiction and it's also known as relativism.

If someone says that all beliefs are true then ask them if the exclusive claims of Jesus are true.  When Jesus said "I am the way, the truth, and the life.  No one comes to the Father except through me." (John 14:6) he wasn't saying all beliefs are true.  This doesn't prove that Christianity is true but it does prove that all beliefs are not true.  Because if anyone denies that the only way to God is through Jesus they are saying that Christianity isn't true.  They are saying they are right and Christianity is wrong.  I've seen people still insist that their belief and mine can both be true even though they deny that Jesus is not the only way to God.  There's only three possibilities in this case:  They are right, I'm right, or neither one of us is right but there is no possibility that we are both right.

Lots of people give Christians a hard time about thinking they are right and others are wrong.  The irony in that is the person who thinks the Christian can't be right is doing the same thing they are accusing the Christian of (thinking they are right and the Christian is wrong).

When I can I'll try to give material I've found helpful on Christian apologetics.  Below are some resources from an organization called Stand to Reason.
