The Lord Almighty, great are your purposes and mighty are your deeds.

Jeremiah 32:1-44
The Lord asked Jeremiah bought the land of his cousin, for Jeremiah is nearest relative and duty to buy it. So Jeremiah spent 17 shekels of silver bought the field at Anathoth from his cousin Hanamel and took the deed of purchase- the sealed copy containing the terms and conditions, as well as the unsealed copy.
Jeremiah prayed to the Lord how this going on?
The Lord reply that I will restore their fortunes, I have brought all this great calamity on this people, so I will give them all the prosperity I have promised them. Once more fields will be bought in this land.
The Lord Almighty, great are your purposes and mighty are your deeds. Your eyes are open to all the ways of men; you reward everyone according to his conduct and as his deeds deserve.
Why?
In Jeremiah's time Jerusalem was besieged, there were famine, word and plague, who will buy a field, for all of these will be gone, it was waste money to buy a field. God's words and Jeremiah bought this field is a prophesy for show what the plan of God will do on this land.
It is 588/7: Jerusalem is under siege, and Jeremiah's hoe town, Anathoth, in enemy hands. Cousin Hanamel is some optimist, coming to the imprisoned prophet to try to sell land at a time like this!
Amazingly, Jeremiah buys- and his purchase shouts the message:'God has a future for Judah. 'Everyone in the city must have heard about it. Jeremiah acts under orders from God; only afterwards does he admit his puzzlement.
In answer God outlines his immediate, and his ultimate purpose for the nation.
Baruch, Jeremiah's secretary, makes his first appearance in verse 12, then in chapters 36, 45
How?
Servant of the Lord do something is sign from the Lord, but from perspective of human likes a fool man, for His eyes and His mind is beyond all of human being. Follow the words of the Lord is good to us forever.
