 John 12, Then Jesus spoke to them, saying, I am the light of the world. He who follows me shall not walk in darkness, but have the light of life. Verse 14, Let not your hearts be troubled. You believe in God, believe in me also. 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.
