" In preparing for the holy instant, do not attempt to make yourself holy to be ready to receive it. That is but to confuse your role with God’s. Atonement cannot come to those who think that they must first atone, but only to those who offer it nothing more than simple willingness to make way for it. Purification is of God alone, and therefore for you. Rather than seek to prepare yourself for Him, try to think thus:
I who am host to God am worthy of Him.
He Who established His dwelling place in me created it as He would have it be.
It is not needful that I make it ready for Him, but only that I do not interfere with His plan to restore to me my own awareness of my readiness, which is eternal.
I need add nothing to His plan.
But to receive it, I must be willing not to substitute my own in place of it. "

- Jesus Christ in A Course in Miracles, Chapter 18, IV
