Tough questions from kids: Why did Jesus go to Heaven instead of staying here on earth?

Jesus' home is in heaven, so it is not surprising that He would leave the earth and go back to his Father.  Jesus also went to heaven to prepare a place for us. When He left, Jesus sent the Holy Spirit to be with us. The Holy Spirit can be everywhere because He lives inside all people who have trusted in Christ as Savior.

I wandered lonely as a cloud
that floats on high o'er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze.

Continuous as the stars that shine
And twinkle on the milky way,
They stretched in never ending line
Along the margin of a bay:
Ten thousand saw I at a glance,
Tossing their heads in sprightly dance.

The waves beside them danced; but they
Out did the sparkling waves in glee;
A poet could not by be gay,
In such a jocund company;
I gazed and gazed - but little thought
What wealth the show to me had brought:

For oft, when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
which is the bliss of solitude;
And then my heart with pleasure fills,
And dances with the daffodils.
~William Wordsworth
