The old testament of the Holy Bible has a promise about lions that I like, but it still seems like a long way off.
Isaiah 11:6-9
6 "The wolf also shall dwell with the lamb,
The leopard shall lie down with the young goat,
The calf and the young lion and the fatling together;
And a little child shall lead them.
7 The cow and the bear shall graze;
Their young ones shall lie down together;
And the lion shall eat straw like the ox.
8 The nursing child shall play by the cobra’s hole,
And the weaned child shall put his hand in the viper’s den.
9 They shall not hurt nor destroy in all My holy mountain,
For the earth shall be full of the knowledge of the Lord
As the waters cover the sea.
