If you think your church is doing good work, you give.
The church I grew up in closed for lack of funds. The preacher never lived large, they weren’t taking more than people wanted to give.
I would never give money to a mega church, but I have donated to UU churches as an adult.






Possibly possible is redundant, but possibly doable might convey what you mean to say.
Necessarily needful might work as a synonym.
