1. John Newton
2. Robert Murray McCheyne
3. Charles Spurgeon
4. Richard Sibbes
5. Jeremiah Burroughs
6. Athanasius
7. Jonathan Edwards
8. Martin Luther
9. C.S. Lewis
10. John Bunyan

Almost making the cut: Augustine, Alexander Whyte, Horatious Bonar, Martin Lloyd-Jones, Samuel Rutherford, Irenaeus, John Owen. 

My rationale:

John Newton is amazing and really gets grace.  McCheyne intrigues me.  Spurgeon is, well Spurgeon.  Sibbes would teach me grace.  Burroughs has an amazing name and would teach me about joy in Jesus.  Athanasius I’ve always wanted to know more.  Why is Edwards only #7?  Because he was a brilliant man, really loved Jesus, but I do not think would actually be a very good mentor.  Martin Luther is #8 because he’d scare me and probably get me drunk.  C.S. Lewis would teach me how to write and think.  And John Bunyan would be like reading the Bible.  And Apollo Creed did not make the list because he is not dead. 

Who would be your top 10?  Mine will probably change in a few years.
