What can you tell Him for you would not be interested in the things you did on earth, nor would you even bother to ask Him how He created anything, for you are out of the flesh now, and the things we thought while in the flesh, and curious, and the things we did on earth we would not care about anymore, and would not be concerned about it.
The only thing you would say is I love you, I praise you, I worship you, and such things will come out of your mouth all to the delight of God.
Rev 5:11 And I beheld, and I heard the voice of many angels round about the throne and the beasts and the elders: and the number of them was ten thousand times ten thousand, and thousands of thousands;
Rev 5:12 Saying with a loud voice, Worthy is the Lamb that was slain to receive power, and riches, and wisdom, and strength, and honour, and glory, and blessing.
Rev 5:13 And every creature which is in heaven, and on the earth, and under the earth, and such as are in the sea, and all that are in them, heard I saying, Blessing, and honour, and glory, and power, be unto him that sitteth upon the throne, and unto the Lamb for ever and ever.
Rev 5:14 And the four beasts said, Amen. And the four and twenty elders fell down and worshipped him that liveth for ever and ever.
That is what will be coming out of your mouth, for nothing else is necessary to speak about.
Rev 6:9 And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held:
Rev 6:10 And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?
Rev 6:11 And white robes were given unto every one of them; and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they were, should be fulfilled.
Although you may say this if you are there before Jesus puts the world down.
Right now we would have things to ask God, and tell Him, but in heaven we will not care unless it is worshipping God, and this applies to this heaven now, for when the saints are at the new heaven and new earth, the New Jerusalem, the former heaven and earth shall pass away, and they shall not be remembered, nor come to mind, for they are associated with sin and rebellion, so the saints will know nothing prior to the New Jerusalem, and will feel like they have always been there and nowhere else, and only charity, love in action, and the saints, will be the only 2 things in the New Jerusalem out of the former earth.
