"...in accordance with the riches of God’s GRACE He made known to us the mystery of His will... to bring unity to all things in heaven and on earth under Christ…according to the plan of Him who works out everything in conformity with the purpose of His will." (Ephesians 1:7-11).
God knew from the beginning that Jesus will save humanity from their sins and bring unity to all things.
I suppose that is why we are instructed to pray for ALL humanity, not just the people we like.
"I am entreating, then, first of all, that petitions, prayers, pleadings, thanksgiving be made for all humanity, for kings and all those being in a superior station, that we may be leading a mild and quiet life in all devoutness and gravity, for this is ideal and welcome in the sight of our Saviour, God, Who wills that all humanity be saved and come into a realization of the truth. For there is one God, and one Mediator of God and humanity, a Man, Christ Jesus, Who is giving Himself a correspondent ransom for ALL." (1 Timothy 2:1-6)
I do not get to vote on who gets saved - and neither do you! Yet, it is my sincere belief that when the plan of God is consummated, all creation will have been saved out of death to enter the New Heaven and New Earth,
"Then I saw a new heaven and a new earth, for the old heaven and the old earth had disappeared. And the sea was also gone. And I saw the holy city, the new Jerusalem, coming down from God out of heaven like a bride beautifully dressed for her husband. I heard a loud shout from the throne, saying, “Look, God’s home is now among his people! He will live with them, and they will be his people. God himself will be with them. He will wipe every tear from their eyes, and there will be no more death or sorrow or crying or pain. All these things are gone forever.” And the one sitting on the throne said, “Look, I am making everything new!” And then he said to me, “Write this down, for what I tell you is trustworthy and true.” (Revelation 21:1-5)
