I am going to focus more on a sermon by John Macarthur (which I, sadly, don't have a link for). John was talking about some statistics he had seen about sex.
There are some good stats from the US government, probably similar to what John was looking at.
An average couple has sex for a few hours a week. A really active couple might have sex for a few hours a day (7-14 hours per week).
Compare that with:
- 56 hours per week sleeping (33%)
- 40 hours per week working (24%)
- more than 17 hours watching TV (5.1*.5*7)
- 8 hours eating and drinking
Now imagine that someone would reject the Good News of salvation, because it would interfere with their watching television. Or the way they drive to work. It would be ridiculous.
Sex is less of a percentage of our day than any of these things.
Yet, for sex, people would turn the world upside down. Reject Christianity, the Bible, hearing the Good News, even friendly relations with other people.
