Give to your mission Board ... if you don't have one ...
Give to mine.
In the 60's I heard about people volunteering to go to India to teach how to make better, more indestructable houses and dig wells and such and that it had been some ten years now and the entire project was a failure because foreign people don't want foreign ways ... they want food and money.
Politicians steal both and nothing happens.
So let's teach them to go to heaven .... they'll understand later ... God's Promise !
You don’t always know every pitfall till you try. Many missions do both earthly and heavenly blessings. God blesses even “failed” trials. But there is a point beyond which God tells us not to be bull headed about keeping up with an approach that only fails. Don’t waste resources casting pearls before swine.
It’s reasonable that if you are a small-o orthodox Christian church you should ask missions to be small-o orthodox as well.
