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.
