Because Jesus said so;
“Let not your heart be troubled:
Ye believe in God, believe also in Me.
In my Father’s house are many mansions:
If it were not so, I would have told you.
I go to prepare a place for you.
And if I go and prepare a place for you,
I will come again, and receive you unto myself;
That where I am, there ye may be also,”
John 14:1-3
