Pray and repent of your sins now before the 3 days of darkness comes. No one is promised a tomorrow unless God gives it.
Have a plan in place so that Lord willing, when the aurora’s appears your family/friends know exactly what to do, where to go, and how to get there before the 3 days of darkness fully descends.
If you can’t make it home or to a building, then stay in your vehicle. I recommend all to pray about keeping 3 days of food, drinks, and dark thick blankets. You will need to keep your head covered with the blankets from what is occurring in the darkness. And pray in Jesus Christ’s Name!
A person/persons caught out in the darkness without any protection in my understanding, no matter who it is will be torn into shreds by the demons, nephilim, and evil fallen angels that are released after being imprisoned and bound for so long. Please pray about this in Jesus Christ’s Name. (This is why the warning from Father God is given out of love about this in advance.)
A true Child of God who loves Jesus Christ and living a pleasing, holy an obedient life in Him doesn't have any reason to be afraid of the coming 3 days of darkness. These are those who will have some form of electrical power provided by our Father God as the Israelites did in the land of Goshen during the 3 days of darkness that covered the land of Egypt during Moses and Pharaoh’s days. (Exodus 10:21-23)
When the darkness comes and you find yourself without some form of electrical power and only able to use candlelight, this is a sign that you’re still being protected by Father God, but you have been found with sin in your life. Otherwise, you would have somehow had use of your electrical power.
This is time that should be spent by the true believers of Jesus Christ in prayer, reading the Word of God, and seeking for the salvation of others.
Lock all doors and windows, close all drapes and blinds and/or cover windows anyway you can, like taped cardboard, black plastic, towels, etc. if Jesus Christ leads you to do so. This is for those who might be in candlelight or have unsaved or small children that may try to open the doors or windows. Some of the evil demon spirits could be mimicking someone they know and love. If someone who isn’t spiritual prepared in Jesus Christ and isn’t accustomed already to seeing demons and such like, the shock of the horror of what they are seeing will cause many to lose their sanity of their minds and could cause heart failure.
If you find yourself by candlelight, then you will most likely hear the demons, Nephilim, and fallen angels screaming outside or their mimicking voices as someone you love or know professing to be trapped outside and begging to be let in. They are trying to trick you to open a door or window. IN JESUS CHRIST’S NAME, DO NOT OPEN THE DOOR OR WINDOW! This will allow this evil outside to enter the place you are located at.
The darkness is of the outer darkness and is a thick darkness that is seen with spiritual eyes. Your physical eyes will see nothing except blackness. It will feel as if it is alive to the sinner and backslider. Many hearts shall fail them in fear of what has come. *Again, the true child of Jesus' Christ has no reason to fear these things because they stand in the power of His Name and authority.
 During the 3 days of darkness no one will come and go out of the place they are in until it's over. No work. No school. No running errands. No anything for 3 days until Father God lifts the darkness by His holy command.
If you are not sure in your heart where your relationship is with Father God and Jesus Christ, then please pray about having 3 days’ worth of food and drink for yourself and others. Ask sweet Holy Spirit how to prepare in Jesus Christ’s name.
