If God is a figment of my imagination then so is the Bible, and so is the world, because what I find in the Bible tells me exactly what I find in the world. For these to be in such complete agreement, they are either both objective reality, or both subjective delusion.
Now, if they are both subjective delusion, we need not continue, because I already do enough talking to myself as it is! But if they are both real, well, that's a different sort of proposition. Because a book has to have an author. And the Author of this book had to know thousands of years in advance what was going to happen, what the world would be like, and so on, when no one else did.
Big bang? No evidence. Big flood? All kinds of evidence. Evolution? Ridiculous! Creation? That's what the "human genome" guy now thinks. The "hopeful monster" has been slain by Irreducible Complexity.
The "Church" at-large? Predicted well in advance: (2 Timothy 3) . . . having a form of Godliness, but denying it's power!
Holy Christian, be all your name means, and walk in holiness, dedication to your Risen Saviour! There is a faithful remnant, through which God still works His wonders!
And I would be happy to show you to the best of my ability what the Bible says about any objection to faith that you may have.
Love in Christ,
