Leaving The Local Church Has Consequences

I know I have read it here, but after a search I haven't been able to find it...
Someone or perhaps multiple people have claimed that if you leave the LRC for whatever reason there will be consequences (poor health, inability to go on with the Lord, to grow spiritually, etc). Can anyone point me to an exact quote? I am thinking specifically about the physical/health consequences, but any examples are welcome. I am still in the LRC and have never heard such things...
Thanks.
