Will Ex-Christians Like Us Be in Heaven?

I received an email from a good Christian friend of mine who attended a church I preached at. She thinks I'll eventually be in heaven! Isn't she nice!? Any other Christian think this way? Here's what she wrote:

John...I find it so interesting that you have turned such a 180 degree around on your belief in God or who He is..You don't have to carry on this persona with me. I know deep down you know God is a loving God...but now that you have strayed away from him..you would have to eat crow to change your mind ..let alone that you are now married to an Atheist.

It does amaze me also that you do not see that you have been deceived of the truth by Satan himself. You know what he has done to you is very typical of how he operates and how you let your guard down to turn away for God. After all..we all know that the Christian life is very hard..it is the hard path. You have now chosen the easy way to deal.

I do believe in "Once saved aways saved" and although I know you are grieving God's very heart by your actions...and will suffer those consequences...I will see you on the other side someday.
