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

for example, 換教會
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 換教會,
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
加拉太書5:22
聖靈所結的果子，就是仁愛，喜樂，和平，忍耐，恩慈，良善，信實，
23溫柔，節制。這樣的事，沒有律法禁止。
馬太福音 28:18 耶穌進前來，對他們說，天上，地下所有的權柄，都賜給我了。
19所以你們要去，使萬民作我的門徒，奉父子聖靈的名，給他們施洗。（或作給他們施洗歸於父子聖靈的名）20凡我所吩咐你們的，都教訓他們遵守，我就常與你們同在，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
