Since there has been no one on earth who knows what eternity will be like, we have never experienced 'forever'. What is time if it has no beginning or end? I believe this is a 'time', which is not time, 'time' will not be a measurement there, it will cease to exist, it will be a 'space of being', God the Father, His Son, heavenly beings and the saved.

(Scripture does not elaborate much about eternal life.)

Gods word saturates the Soul to such a depth of a true believer, that in normal conversation he/she speaks scripture.
Now it may not be verbatim, paraphrased mostly, but; the word is spoken.
There will be many gifts given to believers, that will not accompany us into the kingdom. They have been used only while on this earth. The medium through which we move here on earth, will not be the same as the kingdom.

Time, will not matter as eternity is forever. The medium which I believe will prevail in the kingdom is love,with thought holding a great importance also. Spatial concepts may also be relative, and used.

One constant of the Spirit realm will be Holiness, of which many of the learned qualities of God are composed. Important will be Obedience out of love for God.
I believe love to be the power, the being, heart or essence of God, one of His many qualities which only the mind of the Spirit will really comprehend.

We see only the limited use of this quality here in mortal bodies. Knowledge and knowing the ways of God will fill the spiritual mind. There will be no limitations of that spirit mind, all of it will be used, to its infinite limits.

Thought, may very well be a concept of communication, as well as the method of transportation and the source of bringing it to pass. I believe the chosen of God will have levels of glory, coinciding with the depth of victories and crowns earned on earth while passing through mortal trials. Nevertheless, the highest, will probably be that of 'Martyr for Christ'.

I also believe that those believers who accepted Salvation, who either chose not to grow in spiritual depth, or who did not have the human element of time with which to learn of spiritual qualities on earth will be required to learn those qualities in eternity. All will have Glorified bodies either at the rising of the dead in Christ, or the meeting of the saints in the air. All will have differing glories, some many, some less, some none.

Choice, will also be a gift of God, and which will always be inherent in a child of God even in the spirit realm. For God himself to deny choice for any being, would be to deny Himself freewill and sovereignty in love.
There will be (Majesties) within those levels of glories only God knows of, He will teach those to all those ready and capable to share in them.

Wisdom, will be a perfecting process, joining much together as knowledge teaches. Only God knows the limits He wishes each of us to go to, for the perfecting of His Spirit children of His kingdom. For if we have tried to become Christlike on earth, would we not also become fully his Sons of God: in His realm?

"Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come."

"And this is the record,that God hath given to us eternal life,and this life is in his Son."
