用比喻的目的

        门徒问耶稣说：“这比喻是什么意思呢？” 他说：“　神国的奥秘只叫你们知道；至于别人，就用比喻，叫他们看也看不见，听也听不明。” (路加福音 8:9-10 和合本)

        And his disciples asked him, saying, What might this parable be?And he said, Unto you it is given to know the mysteries of the kingdom of God: but to others in parables; that seeing they might not see, and hearing they might not understand. (Luke 8:9-10 KJV)

         耶稣用一些普通的言论作为起头，来答复门徒对这个故事的询问。祂把门徒跟其他人作比较：特别强调你们。神国的奥秘是启示给他们的。真秘（mystēria)是那些我们自己永远无法发现，但神已经将之启示出来的真理；这个字在保罗书信中很常见，但在福音书中却只出现在与此有关的经文中。但至于别人，看却看不见，听也听不明；他们听见了比喻，却不明白它们的意义。比喻启示了真理，同时也把真理隐藏起来：它们把真理向诚心寻求的人启示出来，他们不厌其烦的在表面底下挖掘，发现其意义；但它们也把真理向那只以听听故事为满足的人隐藏起来。这很明显是比喻的结果，但耶稣却说这也是它们的目的（叫……）。对那些认真的人而言，比喻是知识的矿场；但对那些随随便便、漫不经心的人来说，它们是个审判。求主怜悯我们，让我们成为谦卑跟随主的人，因为主向谦卑跟随他的人就显出来，向骄傲的人就藏起来，所以我们要不断地求主保守我们的心，始终有一颗谦卑受教寻求的心。

How to fix up sendgrid-python, BadRequestsError

Traceback (most recent call last):
  File "sendmail.py", line 79, in <module>
    response = sg.client.mail.send.post(request_body=mail.get())
  File "/home/errong_leng/.local/lib/python2.7/site-packages/python_http_client/client.py", line 227, in http_request
    return Response(self._make_request(opener, request))
  File "/home/errong_leng/.local/lib/python2.7/site-packages/python_http_client/client.py", line 161, in _make_request
    raise exc
python_http_client.exceptions.BadRequestsError

The easy way is to catch this exception and print out the error body:
try:
    response = sg.client.mail.send.post(request_body=mail.get())
    print(response.status_code)
    print(response.body)
    print(response.headers)
except Exception as e:
    print (e.body)  #print (e.read()) 

Then you can know why bad request error reported, such as:
{"errors":[{"message":"Following RFC 1341, section 7.2, if either text/html or text/plain are to be sent in your email: text/plain needs to be first, followed by text/html, followed by any other content.","field":"content","help":null}]}

{"errors":[{"message":"The subject is required. You can get around this requirement if you use a template with a subject defined or if every personalization has a subject defined.","field":"subject","help":"http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.subject"}]}

{"errors":[{"message":"Each email address in the personalization block should be unique between to, cc, and bcc. We found the first duplicate instance of [errong.leng@gmail.com] in the personalizations.0.to field.","field":"personalizations.0","help":"http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.recipient-errors"}]}
