Jesus spoke often about God’s kingdom. He described it as coming in stages, ending with a future time when the earth will be restored and all those who died will be resurrected to learn how to live righteously. 
Revelation  gives us a very clear and comforting description, full of hope, describing what the kingdom work will have accomplished (Rev 21:4, NLT): “He will wipe every tear from their eyes, and there will be no more death or sorrow or crying or pain. All these things are gone forever.” This means there will be no more physical and emotional pain. No one will cry, because no one will die or hurt each other. Another promise is in the book of Isaiah (2:4, God’s Word Translation): “They will hammer their swords into plow blades and their spears into pruning shears. Nations will never fight against each other, and they will never train for war again.” This means people will turn their weapons into gardening t ools, never fighting again.
Isaiah gives us beautiful promises about people with physical difficulties being healed: (Good News Translation, Isaiah 35:5) “The blind will be able to see, and the deaf will hear.” (International Standard Version, Isaiah 35:6), “Then the lame will leap like deer, and the tongues of speechless people will sing for joy….”
The earth is already beautiful, but some parts have difficult living conditions, like deserts. But Isaiah (35:1, Berean Study Bible) promises: “The wilderness and the land will be glad; the desert will rejoice and blossom like a rose.” Also, (Contemporary English Version, Isiah 35:7) “Scorching sand will turn into a lake, and thirsty ground will flow with fountains…” In other words, the earth will be restored to perfection and all parts will be clean, lovely and livable.
Right now, most of us would never dream of having a wild animal as a pet, but Isaiah (11:6, International Standard Version) says, “The wolf will live with the lamb; the leopard will lie down with the young goat. The calf and the lion will graze together, and a little child will lead them.” None of us will ever have to be afraid of wild  animals like grizzly bears and lions because they will be gentle and tame.
So, what will God’s kingdom be like? The Bible says there will be no death, crying or pain. The desert will blossom like a rose, and people who have physical or mental issues will be healed. Countries will not attack each other and all people will live in peace. God promises this is how His kingdom will be, and we can have faith in His promises because they always come true.
