Why didn't Abraham share with Isaac and Sarah the fact that God had commanded him to sacrifice Isaac?

The commentators say that Isaac knew of the plan in advance, but, his faith being as total as his father's, he had no hesitation about submitting (see, e.g., Kli Yakar and Rabbenu Bahya on Gen. 22:7-8; and Sefer HaYashar Midrash on Genesis, Vayera 18,20,21).

As for Sarah, she and Abraham were a team in their great devotion to God and together converted a lot of people to monotheism ("the souls that they made in Haran" in Gen. 12:5).

Further, God never told Abraham not to reveal the plan to anybody.

So why didn't he talk it over with his wife and son? Did he suspect their faith wasn't as strong as his and would refuse to go along? Anything about that in the Sources?
