13 `Go ye in through the strait gate, because wide is the gate, and broad the way that is leading to the destruction, and many are those going in through it;
14 how strait is the gate, and compressed the way that is leading to the life, and few are those finding it!
Few find the path to heaven; many end in hell.

It means that those who concentrate on it and look for it will find the way to life. Suppose it depends whether your definition of 'life' is 'eternal life' or 'life of the right quality'.
The gates are the gates that lead to pasture. And 'eating' of the pastures (or of anything) in bible langauge is synonymous with taking in something of thought, some form of wisdom.
So those who enter the narrow gate eat of the right pastures, while those who go through the broad gate, eat the same as the same of them, who also go through the broad gate.
There's another reference to this in the Gospel of Thomas I think it is, when Jesus says that anybody who tries to jump the gate or climb the fence, (enter in my any other way than the right way) is surely a 'theif' and a 'robber'. It means that 'getting there by any means necessary' shouldn't be the motive. That's a selfish way to think. Rather, 'if I'm going to do it, I'm going to enter, I'm going to enter the way that it's supposed to be done' is the good way to think about it.
From the greek, I saw the verse like this;
'Come in through the 'closely defined' way, for broad is the gate that leads to ruin, and many are those who are entering through that way'.
Ie. lots of people are going the wrong path. Don't go the same path as them. Go through the closely defined path. Tread the path less trodden.
The point, for me, isn't so much about what happens after death, but about how to actually, actively 'walk' in the here and now.
