However, G-d was insistent: “No, but Sarah your wife shall bear you a son, and you shall call his name Yitzhak  (which means ‘mocking laughter,’ or ‘laughter in mockery’); and I will establish My covenant with him for an everlasting covenant for his descendants after him…” G-d restated His divine purpose a second time, adding to it a time frame within which the promise would come to pass¹³.

Then, and only then did Abraham fully believe G-d for the impossible, holding no distrust whatsoever, and without delay fulfilled the sign of G-d’s covenant with him – to be performed in the flesh of the implement from which proceeds the seed.
 
 

With the sign of the circumcision performed, Abraham had moved onto that “bunny trail” of faith, which believes for the utterly impossible, in hope believing against all hope to see G-d’s promise fulfilled, Who gives life to the dead and calls into existence the things that do not exist¹⁴. 

It was at this moment in time that Abraham’s faith was reckoned to him as righteousness, for all the odds were stacked against G-d’s promise coming true. At that instance Abraham’s footprints began to be carved – like chiseled into rock - into that mountain of faith which cannot be ascended by any other means¹⁵. 

Notwithstanding, Abraham did this time not share with Sarah what G-d had said to him, lest she would judge him being on an absurd “bunny-trail” of his own imagination. Sarah heard of going to have a son by Abraham for the first time from the Lord’s own mouth, while she was inside the tent baking cakes of bread¹⁶. The idea was so ludicrous in her estimation, she couldn’t help herself but laugh, mockingly¹⁷. 

It was then that the Lord spoke words that would silence any doubter, and those who consider the one who believes G-d for the impossible and who in hope believes against all hope to be on a “bunny-trail” or “wild goose chase”:

“IS ANYTHING TOO DIFFICULT FOR THE L-RD? At the appointed time I will return to you, at this time next year, and Sarah shall have a son.”¹⁸

Although Sarah tried to deny that she had laughed, the Lord did not let it pass. She had considered all of this an outrageously ridiculous “bunny-trail” of Abraham’s vivid imagination, but the Lord “nailed” it by giving a definite time.

Twenty-three years had passed, and now that they were too old to bring forth a child in their own, natural strength - NOW the Lord confirmed the promise with His own appearance, and a date.

This was no longer a “bunny-trail.” It was exactly as is written, that “faith is the assurance (the confirmation, the title-deed) of the things [we] hope for, being the proof of things [we] do not see and the conviction of their reality – faith perceiving as real fact what is not revealed to the senses.”¹⁹

In the movie, “Voyage of the Unicorn,” the theme running through it like a red thread, beginning and ending the movie with it is, “Credere vistes” / “Believing is Seeing,” and “Faith precedes the Miracle.” It never said anything about a “bunny-trail.”
