Whenever the Lord God Father in Heaven decides that it is time for the earth to be redeemed, the Lord God Almighty will know that it is his turn to take the helm and to enter the earth realm. It will mean that everyone in the millennial kingdom has made it through the gates to eternity, and now the Lord God Almighty must prepare his eternal kingdom so that they too can enter eternity.
They will include all of the Old Testament saints who did not have an opportunity to be in the millennial kingdom, individuals who are currently alive or who have died during the past two thousand years, who may or may not have received the indwelling Holy Spirit Of God, and anyone else who is seeking God. Those who are currently alive should know that they will never see eternity, and will not have an opportunity to be in God's eternal kingdom unless they are sealed with the indwelling Holy Spirit Of God. They also must be raptured into his eternal kingdom.
The Lord God Almighty El Shaddai
