Maybe we should be careful what we mean by lust (and sex desire).
It’s kind of like talking about fire. It’s wonderful in a furnace, in a fireplace, to give us the degree of heat that we want and need.
It wouldn’t be so peachy keen to kindle it in the middle of a living room floor.
Let me say it again - - without lust and sexual desire there would be no human race.
Giving birth before epidurals was NOT a pleasant or painless experience... and raising children for 20+ years takes more motivation than ‘duty’...
God made us the way we are... and gave us the insights also curb those desires when the time was right...
