36Simon Peter said to him, "Lord, where are you going?" Jesus answered him, "Where I am going you cannot follow me now, but you will follow afterward." 37Peter said to him, "Lord, why can I not follow you now? I will lay down my life for you." 38Jesus answered, "Will you lay down your life for me? Truly, truly, I say to you, the rooster will not crow till you have denied me three times. 1"Let not your hearts be troubled. Believe in God; believe also in me. 2In my Father's house are many rooms. If it were not so, would I have told you that I go to prepare a place for you? 3And if I go and prepare a place for you, I will come again and will take you to myself, that where I am you may be also. 4And you know the way to where I am going." 5Thomas said to him, "Lord, we do not know where you are going. How can we know the way?" 6Jesus said to him, "I am the way, and the truth, and the life. No one comes to the Father except through me. 7If you had known me, you would have known my Father also. From now on you do know him and have seen him."
