1The word that Jeremiah the prophet spoke to Baruch the son of Neriah, when he wrote these words in a book at the dictation of Jeremiah, in the fourth year of Jehoiakim the son of Josiah, king of Judah: 2"Thus says the Lord, the God of Israel, to you, O Baruch: 3You said, 'Woe is me! For the Lord has added sorrow to my pain. I am weary with my groaning, and I find no rest.' 4Thus shall you say to him, Thus says the Lord: Behold, what I have built I am breaking down, and what I have planted I am plucking up—that is, the whole land. 5And do you seek great things for yourself? Seek them not, for behold, I am bringing disaster upon all flesh, declares the Lord. But I will give you your life as a prize of war in all places to which you may go."

Do you want great things in 2018?

You will never receive great things if you believe God is WORKING AGAINST you.

19Therefore thus says the Lord [to Jeremiah]: If you return [and give up this mistaken tone of distrust and despair], then I will give you again a settled place of quiet and safety, and you will be My minister; and if you separate the precious from the vile [cleansing your own heart from unworthy and unwarranted suspicions concerning God's faithfulness], you shall be My mouthpiece. [But do not yield to them.] Let them return to you—not you to [the people]. 
Jeremiah 15:19 (AMP) 

What is your motivation? Are you seeking great things JUST for yourself?

2"Take a scroll and write on it all the words that I have spoken to you against Israel and Judah and all the nations, from the day I spoke to you, from the days of Josiah until today. 3It may be that the house of Judah will hear all the disaster that I intend to do to them, so that every one may turn from his evil way, and that I may forgive their iniquity and their sin." 4Then Jeremiah called Baruch the son of Neriah, and Baruch wrote on a scroll at the dictation of Jeremiah all the words of the Lord that he had spoken to him. 5And Jeremiah ordered Baruch, saying, "I am banned from going to the house of the Lord, 6so you are to go, and on a day of fasting in the hearing of all the people in the Lord's house you shall read the words of the Lord from the scroll that you have written at my dictation. You shall read them also in the hearing of all the men of Judah who come out of their cities.

If you want great things, you have to accept the fact YOU don't KNOW what great things are. Only GOD does.

Unbeknownst to him, Baruch was doing a great thing at the lowest point in his life.
