1 Corinthians says “But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.”
It’s completely futile to try and imagine the capabilities of what God has in store for mankind in the eternity of Heaven.
God knows how many strands of hair are on your head, every thought you have, along with every human at the same time. He’s named every star. He sees every animal from the unnumbered ants to the largest blue whales. He knows every cell in all the matter in the universe and is in control of everything.
From the moment he spoke this universe into existence he knew the exact time his son would be crucified and set the stars in motion to prove it.
“Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure”
He does this while also keeping track of every angel and what they are to be doing which could be as many as the stars.
The last thought I would ever contemplate is being bored in Heaven.
God has always been. Our human minds can’t even fully understand that because everything in our universe has a beginning and an end. What did God do before this universe? What’s his plans after this one is gone?
The most important thing is we worship and give all the glory to God as Psalms 139
13 For thou hast possessed my reins: thou hast covered me in my mother’s womb.
14 I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well.
15 My substance was not hid from thee, when I was made in secret, and curiously wrought in the lowest parts of the earth.
16 Thine eyes did see my substance, yet being unperfect; and in thy book all my members were written, which in continuance were fashioned, when as yet there was none of them.
17 How precious also are thy thoughts unto me, O God! how great is the sum of them!
18 If I should count them, they are more in number than the sand: when I awake, I am still with thee.
