It’s not clear to me what Heaven actually is. How do I know I want to go there?
In all seriousness, can someone describe to me what my day to day will be like?
Try it out. Start living in God’s Kingdom now and see if you like it.
I don't understand. Is heaven the same as earth? Are there no differences?
I don't present myself as an expert on this. I'm someone who is trying to learn more and more. One thing I'm trying to get better at is telling the story. So, this probably doesn't directly address your question, but here it goes...
The basic idea is that there is a hope of a new creation. New creation is more about resetting this world to what it was originally intended to be rather than something that exists somewhere else in the clouds. In Judaism, they talk about tikkun olam, repairing the world. God established his kingdom, took his seat on his throne, and put humans in charge in Genesis 1-2. In chapter 3, we hear how humans get in the way of that plan by trying to do things our way instead of his way. In chapter 12, God partners with Abram and promises to bless the nations through him. The story is trying to get back to Eden. The rest of Genesis is God continuing to work through Abram's descendants despite them reliving Genesis 3 and getting in the way. Despite their mistakes, God continues to work out his promise to Abraham. In Exodus, the Israelites are saved out of slavery in Egypt and enter into a covenant with God to carry out that mission and be a kingdom of priests. They are headed to Canaan because that's where God wants his people to be. It's the crossroads of the world at that time, connecting what we call Africa, Asia, and Europe. As God's priests, they are to represent him to the nations so that the world can be blessed and no better place to do that than where the world travels through. We work our way towards Israel being a kingdom in the land. They fulfill their mission at times and fail at other times. As tends to happen, eventually they have declined into chaos. The kingdom splits, they violate the covenant, they mistreat people, they worship other gods, and they are sent into exile in Babylon. Exile ends and they return to Israel with a renewed desire to obey the covenant since they see that as the reason for exile. Rome arrives and plays the role of Egypt and Babylon. Once again God's people are under the boot of an empire. Jesus arrives and calls them back, like the prophets before him, to the covenant. He stresses the need for obedience to God and says it should all be done through the lens of love. In his interpretation, love is what it was always all about and his followers should live that out. Doing this, Jesus proclaims, "The Kingdom of God is here." That's his overarching message. God's Kingdom is here, originally established in Genesis 1. Live in it. Do what the king wants his people to do. They didn't talk so much about "going to Heaven after you die as a disembodied soul", rather they talked about how to live in the Kingdom now on this earth. They talked about this age and the age to come. The age to come wasn't pictured as something that happens when all of this is destroyed and our souls fly off into "Heaven". The age to come was the messianic age. Through Jesus the Messiah's resurrection, the age to come was inaugurated. Post-resurrection, the apostles go around bringing Kingdom, first to Jerusalem then Judea then Samaria then all the world. The Kingdom of God is being brought to the nations. The promise to Abram is being lived out. As it goes beyond Judea, the Gentiles (nations) are brought into the family covenant. They are now part of Abraham's descendants who are tasked with blessing the world and leading us back to Eden.
I'm sure others will quibble (or outright disagree) with some of those details, but the point is it's a story being played out. God's plan will happen and he wants us to join him, as Revelation paints the picture (originally envisioned by Isaiah) of this ultimate victory of God's Kingdom over the evil empires we've created that oppress, bringing this new creation and rescuing this world. Heaven is less about where it is and more about whose it is. "Kingdom of Heaven" is just an idiom for "Kingdom of God". Heaven is living in God's kingdom. As I've read some people say, "eternity starts now".
