We see introduced in this 27th chapter the symbols of warning. Jeremiah was to make his message so very plain.
Jeremiah was going to be vindicated by the Lord, and vindications are like deliverances. You won't be vindicated much in life's journey; you won’t be vindicated all the time, but you will be vindicated sometimes, and your words and your message and your faith and your stand will be demonstrated to some other person or people to have been absolutely true and right. Treasure it! It's a special consolation for you.
Prophets didn't normally behave this way. This is not a justification today for over-enterprising believers to lurch into drama and all that kind of thing. This is prophecy and the prophet receives special sanction to communicate in this way, and there's no sign of it in the New Testament.
There are people who say, ‘Oh, the Bible is contradicting itself. How can a message be given at the beginning of the reign of Jehoiakim, which isn't to be applied until the reign of Zedekiah with all those years in between? There's a contradiction. No, it cannot be a contradiction. The Bible is given by divine inspiration and is absolutely correct. How can you possibly think – even if you didn't believe in the inspiration of the Bible – that some scribe would have made such an enormous error as this within the space of three verses and got two different kings muddled up in so few words? Obviously Jeremiah was given this message and this visual aid, this piece of graphics to perform, much earlier in his ministry. He may, for all we know, have used it many times. First he is going to be told to send these bonds and yokes to the surrounding nations, and later the same meaningful objects will be shown to Zedekiah. Jeremiah was giving the same warning over an extended period of time.
