i saw this sign as i drove by the social network baptist church and i wonder

what do they mean


it said:

happy people avoid lust


now
this is not a stadium church
but it does have
like
2,000 members or something
and
it has been cold called out to me
as an excellent place to meet people
because they
quote
have a really large and active singles network
end quote

so
what do they mean by lust


the lust that happy people avoid


i just though it was very
strange
