We are sinners and our sin deserves to be punished by being separated from God forever and, what's worse, there's not one thing you and I can do to fix that problem. What if I do good things? That doesn't change the fact that you're a sinner. What if I go to church every Sunday morning, go to a Bible study every Wednesday night, and read a chapter in my Bible every night before I go to bed. Surely that will take care of it, right?
Well, let me ask you a question. Let’s say you were single and you went to a wedding every Saturday and watched it. You also went to a wedding rehearsal every Friday night, and you read a chapter in a book about marriage every night before you went to bed. So you're going to a wedding every Saturday, you're going to a wedding rehearsal every Friday night, and you're reading a chapter in a book about marriage every night before you go to bed. Does that make you married? Of course not. You aren’t married until you make a commitment to a person. In the same way, going to church doesn’t make you a Christian. You must make a commitment to Christ, placing your faith in His death to pay the penalty for your sin.
