The book of John has been giving me a lot of comfort lately.
These things I have spoken to you, that in Me you may have peace. In the world you will have tribulation; but be of good cheer, I have overcome the world.
Let not your heart be troubled; you believe in God, believe also in Me. In my Father's house there are many mansions, if if were not so, I would have told you. And if I go and prepare a place for you, I will come again and receive you to Myself; that where I am, there you may also be.
Peace I leave with you. My peace I give to you, not as the world gives do I give to you. Let not your heart be troubled, neither let if be afraid
John 14: 27
