I have a story. The last local church I pastored, the previous pastor taught tithing. I was on staff while he was the pastor. We enjoyed really good offerings that help support the extensive ministries and charities of the church, its staff, and the building. Nothing wrong with what the money was used for, in my opinion.
But when the pastor moved on and I took his place, I taught that I didn't believe in the law of tithing and that we would depend on the generosity of our hearts to continue what we did.
It was effective and the results were dramatic!
We experienced a drastic decrease in offerings.
I welcome you to join The Lasting Supper! Yes, it's $7/month (you can read why here), but that's a lot cheaper than tithing ;)
