experiment
so that to let him know where he is.

there are 2 advantages offered BY that group:
1. time (no need to be anywhere)
2. money (no need to offer 10%0

TRY 10%-offering to that group for 6 months
CONTINUE to listen to 'amazing grace' from the radio

I don't think he will accept this challenge.

Yes, if there is both 'amazing grace' and 'more money+more time',
who refuse IT????!!!

Clearly
The power to make Jesus to resurrect from tomb IS NEEDED for a person to
accept Jesus Christ as Saviour and Lord,
the same power IS NEEDED for a person to have normal church life
as a member in a local church.
