All little children (and these make up a third part of heaven) are led first into an acknowledgment and belief that the Lord is their father. Later they are brought into an acknowledgment and belief that he is Lord of all, which means God of heaven and earth. It will be made clear below that little children mature in heaven and by means of insights are brought into full angelic intelligence and wisdom.
There can be no doubt among church people that the Lord is God of heaven, because he himself teaches that everything of the Father’s belongs to him (Matthew 11:27; John 16:15; 17:2) and that he has all power in heaven and on earth (Matthew 28:18). It says “in heaven and on earth” because the ruler of heaven rules earth as well, the one actually depending on the other. His “ruling heaven and earth” means our accepting from him everything good that is intrinsic to love and everything true that is intrinsic to faith. It therefore means accepting all intelligence and wisdom, and thus all happiness—in short, eternal life. This too the Lord teaches when he says, “Whoever believes in the Son has eternal life; but whoever does not trust the Son will not see life” (John 3:36). Or again, he says, “I am the resurrection and the life. Whoever believes in me, even though he dies, will be alive, and whoever lives and believes in me will not die to eternity” (John 11:25–26). Or again, “I am the way, the truth, and the life” (John 14:6).
There were some spirits who had acknowledged the Father but whose only concept of the Lord had been that he was a human being like everyone else. This meant they did not believe that he was the God of heaven. As a result, they were allowed to travel here and there and to ask at will whether there was a heaven that did not belong to the Lord. They asked around for some days without finding any.
They were people who placed happiness in glory and in being in control, and since they could not get what they craved and were told that such feelings were not part of heaven, they felt insulted. They wanted a heaven where they could lord it over others and excel in the kind of glory they had had in this world.
