"Let not your heart be troubled; you 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 to Myself; that where I am, there you may be also.
"And where I go you know, and the way you know."
Thomas said to Him, "Lord, we do not know where You are going, and how can we know the way?"
Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father except through Me.

Heaven is a prepared place for a prepared people—a place which we shall find Christ Himself has made ready for true Christians. He has prepared it by procuring a right for every sinner who believes to enter in. None can stop us, and say we have no business there. He has prepared it by going before us as our Head and Representative, and taking possession of it for all the members of His mystical body. As our Forerunner He has marched in, leading captivity captive, and has planted His banner in the land of glory. He has prepared it by carrying our names with Him as our High Priest into the holy of holies, and making angels ready to receive us. Those who enter heaven will find they are neither unknown nor unexpected.
