First, I'd not mention the Zuchini if those are men. Just smile sweetly or leave a note of appreciation. There's something about veggies in cookies they just don't normally eat or appreciate. If they don't want them, give them to a neighbor who's expecting. You're a dear.
Also, they aren't supposed to accept gifts, I'm told. I read that most postmen are ex-military now, trained to watch for folks who might be stronger, bolder Christians and are to report them all. I confronted mine one day and learned that I had read correctly. He was embarrassed to admit it but he did. He was replaced by another more serious and quieter one shortly thereafter. One reason this nation is in the mess it's in is because Christians were told to be silent and were too kind to ignore that demand.
It's time to speak the Truth in love, and pray for all who need it, regardless, because Jesus returns soon just ahead, and it's a dangerous time to do nothing but be silent and let it all happen. "The prayers of a righteous person availeth much."
There's real power in prayer and this nation needs all the help it can get, right? You're wanting to give credit where credit it due, so give all glory to Jesus who is the One who
most deserves it for all the good He has done before this nation tried to kick God out of everything.
God bless you. "-"
