Just as we have seasons in the natural, there are also spiritual seasons, which could be referred to as prophetic seasons. Prophetic season is a period of time ordained by God to perform certain events proclaimed through his prophets. Prophetic seasons share the same characteristics with the natural seasons, they depend on mankind to be made manifest. Thousands of years ago, the Lord said made prophetic statement concerning the destiny of the Israelites that a season would come after they have spent 400 years in captivity; they shall be set free from their captors, leaving the land - Egypt with great wealth. But when the season came, no man was found to enforce it, there was no one to stand in the gap and work it out, even though all the elements of life were ready to fight for the course of that prophetic proclamation. And so the Israelites spent an additional 30 years in captivity until God found a man in Moses. Moses caught an understanding of God’s plan, his eyes were opened to see that the season had come for their release from captivity, this culminated to his longing for change and he started taking practical steps.
In our contemporary times we have seen many similar situations. For instance, when the time was ripe for the liberation of South¬-Africa and India from the oppressions of their colonial masters, until God found a willing vessel in Nelson Mandela and Mahatma Gandhi their liberty was not in view, irrespective of the fact that their season of release had come. God never does a thing without the agency of a man, most a times he often begin by putting concern in our hearts, then that concern will metamorphous from just a concern to compassion then finally a vision.
In Exodus 2:11 - 13 the Bible records that what sparked off the liberation movement of the Israelites was compassion Mosses had for his people. He came out one day to see his people and behold what he saw was their burden, he could not stand the sight, he knew by intuition that his people ought to be free, he saw them as a nation not as slaves; he saw them as a great company of kings commanding extra ordinary wealth and then finally he resolved within himself that not only should they be free but any more second spent in Egypt will be deemed as an insult to their God and their person.
Daniel in his days was not an exception to this attendant condition. The Lord made a prophetic declaration through his servant Jeremiah, that a season of release shall come after his people had spent 70 years in Babylon (Jer. 25:11 - 13 and Jer. 29:10 - 14). But this prophetic declaration could not come to pass until God found an agent in a man called Daniel. Seventy years had passed, it was the season for their release but God needed a man to carry it out on earth. Jeremiah 29:10-15 says:

For thus says the LORD: After seventy years are completed at Babylon, I will visit you and perform My good word toward you, and cause you t o return tot his place.

For I know the thoughts that I think toward you, says the LORD, thoughts of peace and not of evil, to give you a future and a hope.

Then you will call upon Me and go and pray to Me, and I will listen to you.

And you will seek Me and find Me, when you search for Me with all your heart.

I will be found by you, says the LORD, and I will bring you back from your captivity; I will gather you from all the nations and from all the places where I have driven you, says the LORD, and I will bring you to the place from which I cause you to be carried away captive.
