The only thing Jesus ever talked about was the Kingdom of God. Think of it as the Government of God; God's politics of grace; God's alternative to anti-human empire.
Jesus announced the Government of God in disorienting parables about a curious grace and a new kind of justice that upends the established order. Jesus said that with the coming of God's Government, "many who are first will be last and the last will first."
Jesus enacted the Government of God by miracles of healing and provision, the "unauthorized" forgiveness of sinners, and a table practice of radical hospitality.
The Government of God that Jesus announced and enacted isn't about dying and going to heaven. The Government of God is about heaven's politics of grace and justice coming to earth—as Jesus taught us to pray, "Thy Government come, Thy Politics be done, on earth as it is in heaven."
