The way I see this is ... to be Christian, its not because 找心靈記託. It's because its real therefore it offers you things that u can get elsewhere. There are many ways of getting 記託, may be drugs, gambling ... But are u genuinely happy? How are your relationship with others?
I have experienced myself and I have seen others. Being Christians, it has offered me something real, peace, strength, guidance, forgiveness, ... and this can't easily explained.
Equally true, there are other Christians or churches that may upset u for one reason or another, whether right or wrong, I do hope you wouldn't miss the horizon of a huge forrest by a tree that u dislike.
