Kingdom of God within you

Seeking something, to me, says that it is not easily seen, somewhat hidden.
You have to search for it.

"Seek, and you will find", Christ spoke.

He also said, in response to the Pharisees who were asking him "When will the kingdom of God come?", He said, "The kingdom of God does not come with your careful observation, nor will people say, 'Here it is,' or 'There it is,' because the kingdom of God is WITHIN you." (Luke 17:20,21 niv)

...and in the Amplified Bible..."Nor will people say, Look! Here [it is]! or, See, [it is] there! For behold, the kingdom of God is within you [in your hearts] and among you [surrounding you].

A man must be born again to "see/enter" the kingdom of God. It is something you find by the Spirit, and it is there for everyone...it is there for you.

You must become like little children...
