B。人是被造、有限、受玷污
C。上帝是「有位格之真理的本体」
D。独行奇事的上帝
E。「永存的上帝」与「偶存的受造」
F。恶的产生
这个课程的题目 -- “神的预定与人的自由”，是许多人很难明白、很讨厌的题目
，但又没有办法不去思想，也不知道到哪里找答案，所以叫人气得半死。现在请你看看
主题看板上的字，有没有发现什麽特点？“神”和“人”的字体比较活泼，“的预定”

但是，最大的特点是什麽？ -- “人”字比其他几个字都大！ 把“人”字写得那麽大
，把“神”字写得比“人”字小一点，这就是我们不能明白这个题目的原因！

「神的预定与人的自由」这个题目是关系到「主权」与「主权」之间冲突的问题，
关系到「人归回神」的问题，以及「神的旨意」和「神意志中间所定的」是照他成全或
照你成全的问题；所以，许多人把神的道当作是生活中间可有可无的一些点缀，因为他

论时代
━━神的管家计划
一、序言
改革神学院名旧约教授W. Van Gemeren博士正确地指出：神在不同的世代逐步完成其救
恩大计，直至万物皆获得复兴之时，而每一时代总有神作为之特色，与其它时代有别〔
注1〕，但这只是单方面的行动，因在人方面，神向人亦有所要求，人故要向神的吩咐负
上责任，如此才能达成神的计划，所以历世历代属神的人皆可称为“神奥秘的管家”，
“所求于管家的，是要他有忠心”（林前4:1-2）。
过去与现在，不少人对“时代论”这神学课题仍有不少混淆不清，而致误解深种，进而
敌对、漫骂及摒弃，至为惋惜。本课试图解释“时代论”是一门正统的神学教义，对明
白整本圣经的神学信息、神对世人的要求与其管理世界的旨意，大有裨益。
二、“时代”的定义
“时代”一词表面看来似与时间有关，然而从圣经神学观点看，“时代”是一个“神的
管家法制”，兹从三方面探讨“时代”的定义。
A.英文的字义
“时代”（dispensation）乃从拉丁文“dispensatio”（意“分派”）演绎而来；由此
，“时代”这词可包含三个意义：1)分配工作的行动；2)管理工作的准则；3)要求尽职

有关神属性的分类和界定，请参考「神的属性：分类范畴」一表，那只是一种主观
的界分。有些人用一些特殊的分类（属性以外的）来界定神的位格，他们列举各样特性
，如属灵的、人格的、无限量的及永恒的。不少神学家如伯可夫（Louis Berkhof）、
贺智（Charles Hodge）、石威廉（William Shedd）及巴域克（Herman Bavinck），都
根 据韦斯敏德信条（Westminster Confession）的分类；其他神学家如巴士威尔（J
Oliver Buswell，Jr．）及来利（Charles Ryrie）则没有将神的属性加以分类。
我们可对神的属性作以下的定义：「神的属性就是一些与神的概念不能分割，及神
本性中的各样特质。这些特性构成了神向其受造之物各种显现方式的基础和特质。》神
的属性必须与神的作为加以区分。神的属性不会为神「增加」什么；神的属性只表明了

几乎所有的正方介绍预定论的文章都会以强调神的主权开始。在他们看来反方不能接
受预定论主要是因为把人的自由意志抬得过高。强调人的自由意志就是贬低神的主权。
正方的思路是由于人全然败坏，不可能用败坏的自由意志选择归向神，只能抵挡神（这
个在后面《人的全然败坏》那一章中还会再讨论）。所以，必须由神来主动拣选一部分
人，使他们可以信。所以，必须强调神的主权，谁得救与否神说了算，跟人没多大关系
，完全是神的恩典。

佛教的我不懂，就不说了。
虽然每个人对神的认识都各有不同，最后总是要回到经文。我不知道你所谓的神需要满
足是哪些经文得出来的想法。
我记得基督教的神学中认为神有很多特性。其一是不变性(immutability)，神也有自存
性（Aseity）。因为神不受时空限制，所以神是不变的。就是在创世之前的神，也是创
世之后的神，也是现在的神。神没有变化。既然神不变，在世界存在前，神不需要其他
东西就可以存在，所以现在的神也不需要其他东西。
圣经说神造人是为了显示神的荣耀。加上神的不变的特性，神的荣耀没有变化。世界和
人的存在只能是让神的荣耀显示出来。同时神还会分享自己的荣耀。而神虽然分享荣耀
，他的荣耀却不会减少。 |

要说起来Java也很有意思,它给软件开发中从头到尾都套上了大大小
小的框框—pattern.
从architecture到programming. 这的确又是JAVA重用思想在设计上
的体现.这一章主要想谈谈programming中的pattern—idioms.
首先就想说说JAVA中最特殊,最常用的String Class.
它就是Immutable value pattern在JDK中的一个典型例子.在程序开
发中,我们常常会遇到这样一些data
object,我们关心的是它的content 而不是它的identity.
拿一个string object来说,我们只关心它里面有什么character,而不
管它是object A或是B. 对于这样一些object如果它的state是可变的
,那么我们在编程是就会有各种各样的麻烦.先是你必须保证thread

发帖数: 2416 | 39 Short answer: you can't.
Long answer: java parameters are passed by value. when you call change(dObj)
, the reference to dObj is passed by value. So when you assign a different
reference to it from within change(), it gets lost when the method returns.
On top of that, Double is an immutable type, so you can't change its value.
You can return a new Double object from change(), or you can (warning: bad
practice):
change(Double[] pseudoPointer) {
pseudoPointer[0] = 0.3;
} |

public class Storage {
String[] ok;
public set(int index, String value) {
ok[index] = value;
}
}
class Main {
public static void main (String[] args) {
Storeage m = new Storeage();
String mystring = "ok";
m.set(10, mystring);
}
}
there is no way to get the reference and assign it.
String objects are immutable. |

If it's for caching and you are not worried about updating, then
the objects cached can be considered immutable, then two objects
loaded by the same key would be logically equivalent and would stay
that way.
If that's the case, why not just skip synchronization all together.
Worse comes to worst two threads get two equivalent objects, right? |

发帖数: 1879 | 47 It is very possible that you got cyclic triggering of events that caused
long delays and locking etc.
For example, when you call setText for instance, it will try to repaint,
and painting itself will trigger your action. Those all take a while.
There are many things you could try to optimize
1. obviously find a way to update the data w/o triggering redisplay
until ready for update.
2. Use immutable objects that eliminate the need for synchronization. |

发帖数: 280 | 49 Integers are immutable. If you want to affect the value of a Integer
variable, the only way is to create a new Integer object and discard the old
one.
在你这个
a = 1
a.notifyAll();
这里新的Integer的对象出来了，已经不是原来那个a所指的对象，这个时候在notify,
就会出现illegalMonitorStateException
这个题的确是比较阴险的。 |
