if possible, to me, it is always OKAY,
my POINT is: the person who 换 anything HAD BETTER know
what he is doing.

for example, 换教会
I strongly ENCOURAGE anybody do it as soon as possible
if he feels uncomfortable at current church, it is beneficial
to himself and to others, after all, on earth all churches of
Jesus Christ belong to Jesus Christ.
At the same time, I must tell the person who 换教会,
1. on earth all churches of Jesus Christ should do the same things,
as the wife of my pastor summarized the other day, two kids of FRUITS
加拉太书5:22
圣灵所结的果子，就是仁爱，喜乐，和平，忍耐，恩慈，良善，信实，
23温柔，节制。这样的事，没有律法禁止。
马太福音 28:18 耶稣进前来，对他们说，天上，地下所有的权柄，都赐给我了。
19所以你们要去，使万民作我的门徒，奉父子圣灵的名，给他们施洗。（或作给他们施洗归于父子圣灵的名）20凡我所吩咐你们的，都教训他们遵守，我就常与你们同在，直到世界的末了。
as such, don't expect that the NEW church would be much better than the old one,
if you don't change yourself, you are going to be disappointed or despaired before long.
2. you PROMISED to grow with others under the grace of God when you joined that church by your FREE will, now, you abandoned others for your BENEFIT, you broke your own PROMISE
3. next time, when you join a new church, please MAKE your PROMISE with your FREE WILL for REAL
4. may Gog bless you at a new church
