We can only imagine it. No one has seen it. Artists draw pictures of it, but we have no idea what it would be like, what it will be like when all of creation has the knowledge of God. What a difference that will make. It will affect how all of creation interacts with one another. Knowing God will change everything. Here are Isaiah's words as he looks into the future to that day,
Isaiah 11:6 The wolf will live with the lamb,the leopard will lie down with the goat,
the calf and the lion and the yearling together;
and a little child will lead them.
7 The cow will feed with the bear,
their young will lie down together,
and the lion will eat straw like the ox.
8 The infant will play near the cobra’s den,
the young child will put its hand into the viper’s nest.
9 They will neither harm nor destroy
on all my holy mountain,
for the earth will be filled with the knowledge of the LORD
as the waters cover the sea.
Why are all these strange things going to happen? Because all the earth will be filled with the knowledge of the Lord. Apparently we don't have that knowledge now. What a difference knowing God will make for everything. The picture Isaiah paints is vivid. It's surreal. It's inviting. Imagine the perfect day. This will be what it looks like and it's all based on knowing God.
The atheist will tell you that we can only have peace when we all turn away from our notions about god, but just the opposite will be true. It's only when we know him that peace will come for all of creation.
Here is Paul's prayer in Ephesians 1:17 I keep asking that the God of our Lord Jesus Christ, the glorious Father, may give you the Spirit of wisdom and revelation, so that you may know him better.
Why would knowing him better be important? Because it changes how I interact with everyone and everything! Knowing God affects the world around me. It's the only thing that will bring our universal longing for peace into reality. Why will the world suddenly change and become a peaceful place? Because " the earth will be filled with the knowledge of the LORD as the waters cover the sea." It's only when we know God that the world becomes what we always dreamed it would be.
