Then you haven't experienced it. No one who is a Christian will ever say that it is boring.
How do you know? Have you tried it? There are millions of Christians who have a lot of fun being Christian. We just do it with a lot less sin, and, therefore, a lot less problems. Maybe it's only your problems that keep you from getting bored.
What do you think we do all day: sit around fireplaces and read Bibles? We ski, swim, play sports, read, have friends, and problems like anybody else. Christianity is not boring. It is an adventure.
