reflection of agape mobs

on friday, i just was not concentrated enough on what was going on in mobs. was it because i left pca or was it because of myself. but in any case, there was a lot of things i may have been wrong in, but one thing is that leaders should look into what they took in as answers and put in their opinions and put them out so people can debate because their answer is not always right. i believe that christians should not be christians because they had pier pressure, but pier pressure is one of things than can push you into the direction of Christ, but not why you are Christian. in my opinion you should never be angry, unless its sinless, but another reason because we our anger would lead to destruction which means its pointless to be angry. I remember a verse in romans where it says to not take revenge, but let God do it because it is His to revenge (it kind of sounds like its his responsibility or duty)
