Another look at the sowing-reaping lesson

Micah 7:13: Notwithstanding the land shall be desolate because of them that dwell therein, for the fruit of their doings.
We read this verse in family devotions today, and that last part of the verse struck me hard; it was "for the fruit of their doings." The land was desolate, with nothing good or healthy in it, because, as the verse says, the fruit of their doings wasn't very good either. You know, you do reap what you sow, but you also eat what you reap, and if you're not sowing anything good, then you're not reaping anything good, and if you're not reaping anything good, then you're not eating anything good, and if you're not eating anything good, you're going to die.
