Jesus proclaimed that the Kingdom of God was among us. So, while this is not heaven, the fulness of the Kingdom, we do not have to look to the future to see the Kingdom. We can find the Kingdom of God here and now in how we live out the salvation of God.
Based on Luke 17:20-25
Once Jesus was asked by the Pharisees when the kingdom of God was coming, and he answered, ‘The kingdom of God is not coming with things that can be observed; nor will they say, “Look, here it is!” or “There it is!” For, in fact, the kingdom of God is among you.’
Then he said to the disciples, ‘The days are coming when you will long to see one of the days of the Son of Man, and you will not see it. They will say to you, “Look there!” or “Look here!” Do not go, do not set off in pursuit. For as the lightning flashes and lights up the sky from one side to the other, so will the Son of Man be in his day. But first he must endure much suffering and be rejected by this generation.
