Why? Read the descriptions found in bible as a first start.
The purest approach is to appreciate being alive. Then every moment is heaven.
Most people don't know, proving that they actually have not read the bible.
After the claimed rising, read what he does in each of the gospels. See for yourself.
If you're into Jesus, you would do that as a matter of personal choice and not because of what I noticed decades ago.
One can appreciate being alive every moment, while also realizing that this physical, fallen planet is not heaven. With all the deterioration, disease, crime, violence, etc. that is obvious.
According to both the Gospels of Mark and Luke, Jesus was…
…received up into heaven, and sat down at the right hand of God. Mark 16:19
…He was parted from them and carried up into heaven. Luke 24:51
Matthew and John don’t say, but in the book of Revelation of Jesus Christ, John saw that Jesus was in heaven…
After these things I looked, and behold, a door
standing open in heaven. And the first voice which I heard
was like a trumpet speaking with me, saying, “Come up here, and I will show you things which must take place after this.” Revelation 4:1
And I looked, and behold, in the midst of the throne and of the four living creatures, and in the midst of the elders, stood a
Lamb as though it had been slain, having seven horns and seven eyes, which are the seven Spirits of God sent out into all the earth. Revelation 5:6
