What do you think heaven will be like?

I know none of us know for sure but for those of us who believe in heaven what's your concept? My uncle who has since ped, had a near death experience and reached the other side into heaven. He saw his loved ones who had ped before him and they told him how much work is still going on in the next realm. He saw my grandfather who was raising my little cousin who died from cancer at age 3. He (my cousin) was the age he would have been on earth had he lived. They told him much work was being done for the cause of Christ and it continues as we p over to the next realm. This is just a short explanation of what he experienced - he experienced many more things there, especially beauty, peace, and unconditional love. Thanks for your answers. Blessings -
