I recently realized that I wasn’t living in the house that I thought I was.

Last summer I moved into a house bearing the number 15. I love everything about it: the house itself, the neighbours, and the area’s community spirit.

It wasn’t until some months later that I realized that I didn’t actually live at #15: I live at #13. The house next door is #11, and opposite my house is #12. Counting from the bottom of the street, mine is the thirteenth house.

So why didn’t the city call it #13 when it was assigning street numbers to the houses?

In many countries, the number 13 has unlucky connotations. Why? One reason is that there were thirteen present at the Last Supper, including Judas, who would betray Jesus.

Some people are superstitious about this number, and try to avoid its “bad luck” by keeping away from anything labelled 13. There’s even a word for the fear of the number thirteen: triskaidekaphobia.

The result is that many companies and cities fudge their numbering to avoid 13. This is why many hotels and tall buildings seem to lack a thirteenth floor: the elevator buttons skip from floor 12 to 14.

The thirteenth floor continues to exist, as does the thirteenth house on a street: we haven’t erased them. But we just call them by other names. We simply pretend that they’re actually the fourteenth floor or the fifteenth house. Everyone goes along with this fiction because it means we don’t have to face reality. We’re deluding ourselves, of course, but it seems we prefer to live in denial.

We do the same with sin, don’t we?

We call it by other names so we don’t have to face up to the reality of what it really is.
