Hmmm, I dunno, I'm surrounded by married Christians and they have troubles every now and then, the same is advised to them, though. Apparently when it was said "Seek ye first... His righteousness, all these things shall be added." It meant all, including healthy marriage! Maybe depends on the type of Christian.

So I tried the password thing on two browsers, I didn't get
logged out on the one with my old password. BUT, I gave it a few like maybe 15 mins, and it logged out (maybe, just maybe, cookie and session time limit)! So, it does log you out if you change the password!
