燕京大学虽然已经不存在了，但是他的著名校训为「因真理得自由以服务Freedom Through Truth For Service」仍然被基督徒们所记念。
哈佛大学的校训也是「真理」（Veritas，1643年）1650年后更改为「荣耀归于基督」（In Christ Gloriam），1692年则是「为基督、为教会」（Christo et Ecclesiae）。
真理对人是如此重要。 为什么呢？ 因为真理叫人得自由！ 但是，千百年来，人们就一直没有弄清楚到底什么是真理？ 到底什么是自由？ 两者有何关系？ 《约翰福音》第八章中创造和救赎世界的基督把答案告诉了我们。
一、 何为自由？ （Ｖ31-32）
谁是耶稣的门徒呢？ 谁是耶稣的真正的门徒呢？ 你们若常常遵守我的道，就真是我的门徒。
作门徒为何如此重要呢？ 真理必叫你们得以自由。 真理的益处是什么呢？ 让人得自由。
第一， 他们认为自己是亚伯拉罕的后裔; 这样的认知是建立在血缘关系基础上的。 成为亚伯拉罕的后裔是建立在信心连结基础上的，不是靠血缘关系的。
真正的现实是： 1）这些信的人不是亚伯拉罕的后裔; 2）这些信的人是为奴的。 然而，比这个事实更可怕的现实是他们竟然不知道他们在自欺。
耶稣知道这些人的苦境：他们没有自由， 你们是罪的奴仆。 要想摆脱奴役，你必须得死。
3. 属魔鬼的 （V37-38）
作为耶稣基督的门徒，作为相信他的人。 你是否真的有信心？ 真的得了自由？
Scripture: Joh 8:31-38
31 To the Jews who had believed him, Jesus said, “If you hold to my teaching, you are really my disciples.
32 Then you will know the truth, and the truth will set you free.”
33 They answered him, “We are Abraham’s descendants and have never been slaves of anyone. How can you say that we shall be set free?”
34 Jesus replied, “Very truly I tell you, everyone who sins is a slave to sin.
35 Now a slave has no permanent place in the family, but a son belongs to it forever.
36 So if the Son sets you free, you will be free indeed.
37 I know that you are Abraham’s descendants. Yet you are looking for a way to kill me, because you have no room for my word.
38 I am telling you what I have seen in the Father’s presence, and you are doing what you have heard from your father.
Although Yenching University no longer exists, its famous school motto "Freedom Through Truth For Service" is still remembered by many Christians.
The school motto of Harvard University is also "Truth" (Veritas, 1643). After 1650, it was "In Christ Gloriam;" and in 1692 it was "For Christ, for the Church" (Christo et Ecclesiae).
Truth is so important to people. Why? Because truth sets people free! However, for thousands of years, people have not figured out what truth is? What is freedom anyway? What is the relationship between the two? The answer is revealed in Chapter 8 of the Gospel of John.
Focus Points: A. What is freedom? (V31-32)
1. People who believe in Jesus
A person who believes is not the same as a saved person. Volatile faith is abnormal faith, not true saving faith.
The reason why people are erratic in faith is because they do not know, do not understand, do not recognize the object of their faith, do not understand or do not know whether they have the saving faith.
2. The disciples of Jesus
Who are the disciples of Jesus? Who are the true disciples of Jesus? If you always keep my way, you are truly my disciples.
What should the disciples know? 32 You must know the truth, and true disciples who always follow the path of the Lord will know the truth.
Why is discipleship so important? The truth will set you free. What are the benefits of truth? Let people be free.
3. Terrible reality (V33)
From the answers of believers, we can see two major cognitions of themselves: (1) they consider themselves to be descendants of Abraham; this recognition is based on blood relationship. Becoming a descendant of Abraham is based on a connection of faith, not by blood. (2) they think that they have never been a slave to anyone;
The real reality is:
(1) These believers are not descendants of Abraham;
(2) These believers are slaves.
However, the more frightening reality is that they don't even know that they are
B. How to be free:
The prerequisite for freedom is that you know what freedom is and that you have the need to be free.
1. The Servant (V34)
Jesus knows the plight of these people: they have no freedom, and “everyone who sins is a slave to sin.” To be free from slavery, you must die.
The Bible reveals that the wage of sin is death. The tragic fate of the sinners is death.
2. Gain Freedom (V35-36)
True freedom is given by Jesus, and true freedom is given by the Son of God.
Freedom is not something that people can obtain if they want to. Freedom does not come from or is possessed by people.
Jesus can give people freedom, and the freedom He gives is true freedom.
3. Of the Devil (V37-38)
The truth that the Lord Jesus said to these capricious believers.
Jesus made them see that He actually has no real relationship with Abraham. The standard is because these people cannot tolerate the words of Jesus.
Jesus revealed that He came from above, from God.
Ms. Bing Xin, as an alumnus of Yenching University and a teacher afterwards, in her viewpoint: Truth is "love", and freedom is "everything you want, and nothing is not in love". In the name of love, we care for and help each other, which embodies the essence of service.
Education is to use life to influence life. John Leighton Stuart also spent his whole life practicing his school motto - "Freedom Through Truth For Service."
As a disciple of Jesus Christ, as a person who believes in Him, are you really confident, really free?
Jesus Christ is the truth, He is the incarnation of the truth, and those who believe in Him are free! And those who are free will practice the truth and live in freedom!
