In the year 3020, the Lord God Almighty will know with certainty all those who are in the millennial kingdom of God, because they are the ones who will transition into the next eternity, and into the next eternity, and the next. If your spirit tells you now that you will be alive in the year 3020, you are on the right tract. Continue to do and to think righteously, and keep your focus on Jesus Of Nazareth.
If you are in the millennial kingdom of God, yet your spirit that was in you on the day you were born does not confirm that you will be alive in the year 3020, it means that despite being sealed with God's indwelling Holy Spirit, you are continuing to do evil. Your spirit has not yet fully resurrected.
Ask the indwelling Holy Spirit Of God to show you every area of your life that needs to become transformed, including your mind, and begin the transformation process today. The Lord God Almighty is El Shaddai. The Lord God Almighty is true, and he is faithful.
The Lord God Almighty El Shaddai
