Every person has the opportunity to get to know God. If you decide not believe in him you are rejecting him. All the good works that have been done with out God in mind are not your ticket in. Read Romans 3:23 and Romans 6:23. These two verses really speak to my heart regarding this question <3
You are judging based on your religious upbringing. How do you know that you know God? There are hundreds of religions, many claiming they are the only true path to God. They can't all be right in that statement.
Or are you saying you have God's home address and maybe phone number?
