What is the kingdom of heaven? “Except you become as a little child you shall not see the kingdom.” Jesus said “The kingdom of God is within”.
The child spirit is within.
Here is my personal interpretation of the verse above:
I honor the innocence of my spirit, a spirit that is filled with wonder and imagination. Who sees no separateness, only connectedness to all things living. With my child-like spirit, I enter a magnificent place called heaven, nirvana, pure JOY. My spirit dances and plays on God’s playground, some have named heaven.
