They can’t understand the truth. They are separated from the life of God. That’s because they don’t know him. And they don’t know him because their hearts are stubborn.
Christ did not enter a sacred tent made with human hands. That tent was only a copy of the true one. He entered heaven itself. He did it to stand in front of God for us. He is there right now.
