I have known the truth for the majority of my life. Since the age of three, to be exact, even if I did not understand it. How is that possible? Because I grew up around the truth. It was in the movies I watched as a little girl, in the books I read as a young student, and in the stories told to me by my grandparents. I've known about it because of the people I was reared around. By their example; and their faith. To know what I've learned is to understand the truth, and the truth is: 

There is only one true God.

We are all sinners headed to eternal damnation. 

And there is only one way to heaven.

"The fear of the Lord is the beginning of wisdom, and knowledge of the Holy One brings understanding." - Proverbs 9:10
