Creating A God Who Doesn't Exist

This is a much bigger problem than atheism in modern America, despite all the attention atheism gets among Evangelicals:

"We may be responding not to the real God but to what we wish God and life to be like. Indeed, if left to themselves our hearts will tend to create a God who doesn't exist." (Tim Keller, Prayer [New York, New York: Dutton, 2014], 62)

For some ideas about how to address the problem, see here for a brief summary and here for a lengthier discussion (including in the comments section of the thread). The thread here (again, including the comments section) on whether Christianity is a demonic deception makes some relevant points as well.
