Quote from A Course in Miracles Text Chapter 20 - THE VISION OF HOLINESS.

T-20.II.3. Each gift is an evaluation of the receiver and the giver. 2 No one but sees his chosen home as an altar to himself. 3 No one but seeks to draw to it the worshippers of what he placed upon it, making it worthy of their devotion. 4 And each has set a light upon his altar, that they may see what he has placed upon it and take it for their own. 5 Here is the value that you lay upon your brother and on yourself. 6 Here is your gift to both; your judgment on the Son of God for what he is. 7 Forget not that it is your savior to whom the gift is offered. 8 Offer him thorns and you are crucified. 9 Offer him lilies and it is yourself you free.
