This Course Will Be Believed Entirely Or Not At All

"This course will be believed entirely or not at all.  For it is wholly true or wholly false, and cannot be but partially believed.  And you will either escape from misery entirely or not at all.  Reason will tell you that there is no middle ground where you can pause uncertainly, waiting to choose between the joy of Heaven and the misery of hell. Until you choose Heaven, you *are* in hell and misery.
There is no part of Heaven you can take and weave into illusions.  Nor is there one illusion you can enter Heaven with.  A savior cannot be a judge, nor mercy condemnation.  And vision cannot damn, but only bless. Whose function is to save, will save.  *How* he will do it is beyond your understanding, but *when* must be your choice.  For time you made, and time you can command.  You are no more a slave to time than to the world you made."

"Salvation and the Holy Relationship," "Your Brother's Sinlessness"
"Remember that you learn not for yourself alone, no more than I did.  It is because I learned for you that you can learn of me.  I would but teach you what is yours, so that together we can replace the shabby littleness that binds the host of God to guilt and weakness with the glad awareness of the glory that is in him.  My birth in you is your awakening to grandeur.  Welcome me not into a manger, but into the altar to holiness, where holiness abides in perfect peace.  My Kingdom is not of this world because it is in you.  And you are of your Father.  Let us join in honoring you, who must remain forever beyond littleness."
