Dan 1:5-6 And the king appointed for them a daily provision of the king's delicacies and of the wine which he drank, and three years of training for them, so that at the end of that time they might serve before the king. Now from among those of the sons of Judah were Daniel, Hananiah, Mishael, and Azariah.
God had shown to Daniel and the Israelites
the vision that
1. the Babylonians would conquer Jerusalem and burned it to the ground,
2. the Israelites would be taken as captives to Babylon for seventy years,
3. not to listen to the false prophets.
and also their missions that
1. they must serve the Babylonians,
2. settle down and bear children,
3. live in peace with all.
With these visions and missions, the Israelites were able to live peacefully in exile while joyfully and faithfully serving the Babylonians.
Whereas this captives from the other nations will be living in sorrows, pains and hatred for the death of their beloved family members and friends, the destruction of their cities and countries and the present sufferings. They would be planning revenge and rebellion.
Amos 3:7-8 Surely the Lord GOD does nothing, unless He reveals His secret to His servants the prophets. A lion has roared! Who will not fear? The Lord GOD has spoken! Who can but prophesy?
God kept His words that He would reveal His secrets and plans to His prophets before He put them into action.
Note - many prophets had prophesied the destruction of Jerusalem because of the Israelites refusal to repent of their sins, idolatry, abominable practices, etc
Hos 4:1-3 Hear the word of the LORD, you children of Israel, for the LORD brings a charge against the inhabitants of the land: "There is no truth or mercy or knowledge of God in the land. By swearing and lying, killing and stealing and committing adultery, they break all restraint, with bloodshed upon bloodshed... My people ask counsel from their wooden idols, and their staff informs them. For the spirit of harlotry has caused [them] to stray, And they have played the harlot against their God.
Heb 1:1-2 God, who at various times and in various ways spoke in time past to the fathers by the prophets, has in these last days spoken to us by His Son, whom He has appointed heir of all things, through whom also He made the worlds;
I thank God that our Lord Jesus has revealed all the coming events in the prophecies found in the four Gospels, Epistles, etc.
I thank God that He has also given us the Spirit of truth to teach us all things and guide us into all truth.
John 14:26; 26:13 "But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all things that I said to you... However, when He, the Spirit of truth, has come, He will guide you into all truth; for He will not speak on His own authority, but whatever He hears He will speak; and He will tell you things to come."
Mission for Endtime Christians
Similarly, like Daniel, Christians who know their God and given the vision of the coming World War 3 will be looking forward to do great exploits. They know that God with signs and wonders, will empower them to care, nurse, feed, heal, etc. for all those badly affected by World War 3 resulting to hundreds of millions being saved. They will be rejoicing while discipling all these new converts so that they can overcome the coming deceptions of the Antichrist during the wrath of Satan and are found worthy to become the bride of the Lamb.
