GENESIS 2:6
 

but a mist went up from the earth and watered the whole face of the ground. [Genesis 2:6 NKJV]
 

But there went up a mist (fog, vapor) from the land and watered the whole surface of the ground– [Genesis 2:6 AMPC]

Waiting or expecting a descension of water from heaven, but instead there was an ascension from the earth. A good man will be satisfied from within himself according to "Proverbs 14:14."
 

In this Bible verse above, the earth that could not make plants to come up from within it happened to be the one making mist to come up from within it. It happened that the earth had not fully utilized all the capacities or strength God endowed it with, while looking up for external helper or rain from outside, whereas what the earth was looking for from outside was there hidden within it. It's important to know how much God already deposited or given us power to produce from within us, lest we be craving or complaining for what we need from outside when we already have abundance of them within us. The dew did not have to come from outside or from heaven, but from inside out.
 

There's a reason God prefers putting living waters inside us, springing up from within us, rather than showering us with showers of blessings sent from above down to us.
 

[John 4:13-15] — "Jesus answered and said to her, Whoever drinks of this water shall thirst again: But whoever drinks of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life. The woman said to him, Sir, give me this water, that I thirst not, neither come here to draw."
 

That's how to know the Earth has become "Paradise:"
 

*1* When instead of the earth to depend on heaven for supplies or help such as rain or blessings from above, the earth would be self-sufficient, independent and helped from within herself.
 

*2* When instead of the earth to depend on help of a man to till the ground before the earth can be productive, the earth would rather have the man to enjoy the garden or productivity she had by God's help only, without the man being used or helping after all.
 

So the man thinking he was coming to help, but realized that God already helped and the earth had become fruitful and productive without the man's effort involved. And yet the earth would allow the same man or husband to be in charge and enjoy the fruits of where he did not sow, because the earth is paradise for man and her ground is not yet cursed against man.
 

These were the signs of paradise the earth became in the first heaven, when things would just be working themselves out for mankind, and the only job man had to do was to value, appreciate and keep all that the Lord and the ground (earth) were bringing and doing for the man's sake. Then it was not the earth that's needing a helper; but the man that was supposed to be the helper to the earth suddenly became the one needing helpers or suitable helper meet for him. So instead of man serving the earth, the Lord made all things for the service of the man. Man needed not labor to eat, for eating whatever he desired was freely given to the man except one forbidden Tree he must not eat in Obedience.

Here's Paradise, where:

[Romans 8:28] — "We know that all things work together for good to them that love God, to them who are the called according to his purpose."
