I’ve been doing a little thinking about the whole mess at Wheaton College.  One of the professors made the theological and career-altering mistake of saying Christians and Muslims worship the same God.  It helps me to think in very simple terms.  Try this with me.
My name is Jim.  I want you to know a little about me. I am a 53 year old man.  I am a husband of Kris and I have 4 sons.  I am the son of Marvin and Betty.  I am the brother of Scott and Mark.  I like to ride motorcycles
If you’re in Starbucks one morning and you get into a conversation with the older gentleman sitting by the window.  It might come up in the conversation, that he knows “Jim.”  (After all I’m in there a lot).  Instantly you two have something in common because you both know Jim.
I don’t know why you would, but you start telling “Jim” stories.  And as you talk, he describes Jim as a “young guy in his early 30’s.”  He continues, “He has a son and a daughter.”  And “He rides a bicycle here to Starbucks every morning.”  And finally he says, “Yes, and the Jim I know is named Bob.”
One thing has become clear… he’s not talking about the same Jim!  In fact, it’s not Jim at all.  What you thought you had in common, you didn’t.
The God of Christians is the One who has revealed himself as Father, Son and Holy Spirit.  His Word is contained in the Scriptures of the Old and New Testaments.  He calls Himself Yahweh.  His Son, Jesus is the Messiah, God incarnate, who redeemed the world through His death on a cross and secures new life for people through the power of resurrection.  He invites people to trust Him through faith and promises to give grace, forgiveness and life forever in return.
We can call anyone, or anything god.  We can create our own stories, or follow those that have been around for thousands of years.  Just because we call someone a god doesn’t mean He’s the God of Christianity.  Allah is not the God of Christianity.  If you know His story, as He tells it in the Bible, you know He can’t be.
