What does heaven look like?

What I understand from this Brother Eli's video:

Though we do not have a complete description of the entire heaven yet, there are some parts of it that the Bible describes.

Rev. 4:1-11 is where Apostle John, in the spirit saw someone looking like a Jasper of sardine stone sitting on a throne. Before the throne were 24 seats on which 24 elders in white garment sat.

There was also the ark of covenant. John also saw the tree of life. There was a river of crystal water which is the river of the water of life.

Moses also saw it on Mount Sinai but, he did not write down all he saw.

A surprise awaits those that will go to heaven, and we know it is going to be a joyous experience as never seen before.

Rom. 8:18 says the sufferings of the present time cannot be compared to the glory that shall be revealed in us. And, 1Cor. 2:9 says eye hath not seen, ear hath not heard, and even the heart hath not conceived what God has prepared for those that love him.
