providing protection against HIV.1

我想,首先是,神提供的不仅仅是一个“道理”,而是对生活的各个层面的指导。
其次,我也相信,有一些美好的圣洁的生活可以通过其他的指导和自己的努力来达到,
但是问题在于,这些指导,并不consistent,有时候甚至彼此矛盾。
很多讲小孩教育的书都提到,如果父母两个人在教育小孩的方法上不consistent,结果
会使小孩子很困惑,不知道要听谁的,或者是在不同的事情上在父母之间选择一个合自
己口味的。同样的道理,在这个世界上寻求不同的指导,使很多人困惑,不知道人生的
方向。
我作为基督徒,非常深刻的体会就是,在我生活中的每个细节,我都可以从神那里找到
指导,他的指导是consistent的,不会在这件事情上这样,在那件事情上那样。所以我
不再困惑,我可以把自己交托给神,因为知道他的指导总也不会落空。

宗教对犯罪率的影响
更加信仰基督的地方有更多的社会弊病和犯罪。这是格雷戈里。保罗在学术杂志《宗教
与社会》上发表的初步结论,这个杂志是内布拉斯加州一所教会学校的学报。
http://moses.creighton.edu/JRS/2005/2005-11.html
研究表明,基督教统治的美国南部和中西部地区,社会弊端和犯罪更严重,谋杀,性病
,死亡率更高。这项研究还表明,美国的犯罪率和基督徒比例,比其他发达世界国家都
高得多。
无法回避的现实是,基督教的教条更合适一个病态的社会。宗教狂热分子和极端主义比
毒品危害更大。
理性的人认识到基督教神话的荒谬可怜,而基督徒,尤其是福音派,或原教旨主义者,
不过是一些伪君子,用宗教作为武器来贬低他人。
格雷戈里。保罗的研究首次量化了基督教教义产生的社会效果。不只是基督教,一切狂
热的邪教都可能会有类似的邪恶效果。
当然,天主教会花了几百年压迫陷入贫困和苦难的老百姓。穆斯林有同样的呼吁
:暴力,复仇,排斥和压迫。
理智的人会奇怪宗教神话的诞生。
在美国,宗教=残酷。

论天国

一、序言
法国神学家Georges Pidoux在其名著“神的临在”一书内谓,“旧约神学建立在两大确
定的根基上,一是神已在历史内临到人间,一是神将来再临人世”〔注1〕。神在历史内
的出现称为“显圣”或“临格”(theophany),神在将来显圣的时代称作“耶和华的日
子”、“主的日子”、“那日”,这日是神审判列国,惩罚罪行,炼净选民,继又为选
民伸冤,建立神国的时代,此日不只是以色列人翘首渴待来临的日子,更是历世万代圣
徒长久等待出现的时刻(但2:4-45;诗2:1-9;赛4:2-6;珥2:31;3:16-20;番3:16-20
;摩9:11-15;亚12:4-9;启19:15)。
旧约与犹太教的神学思想就表露这种盼望,这盼望分为二翼,相辅相承,一是信赖神在

来自主题: TrustInJesus版 - 再来提问一个信奉的问题

回应:
一、注意“长老”不是“老年人”可能是年轻人或中年人。请长老抹油祷告是很正常的
,任何相信圣经的教会都会有人相信并实践的。
二、我不清楚怎样解释‘“圣经”“新约”明确要求女人在教会要“闭口不言”’。

例如,哥林多前书十一章,
4 凡男人祷告或是讲道(讲道或作说预言下同),若蒙着头,就羞辱自己的头。 5 凡
女人祷告或是讲道,若不蒙着头,就羞辱自己的头。因为这就如同剃了头发一样。 6

If boils down to data consistency vs scale (sacrificing consistency).
DC and scale cannot co-exist. RMDBs such as SqlSv offers consistency

is similar to the concept of UMUE (uniformly minimum-variance unbiased
estimator). A consistent but biased estimator does not belong to the class
of LUE, thus can never be the best in the class. Meanwhile, a BLUE can be
