The Wisdom of Unconditional Love
The verse, "Yitzchak loved Eisav," is counterintuitive. It implies that Yitzchak loved Eisav, his wayward son and makes no mention of his love for Yaacov, his righteous son. Yitzchak realized that since Eisav's nature was so wild, he would rebel if he disciplined him. Therefore, "Yitzchak loved Eisav," meaning that he wisely chose to give his son unconditional love. Yitzchak hoped that the love and honor that he granted to his son, would eventually seep into Eisav's heart and stir him to rectify his conduct.
In the end of days, all of our great ancestors will plead for the deliverance of Klal Yisrael. However, HaShem will not accept their prayers. Finally, Yitzchak will come before HaShem and say, "Save my people, on the merit of the unconditional love that I gave to my son, Eisav." HaShem responds, "I will have mercy on Klal Yisrael, just as you had mercy on your son, Eisav."
Visualization: Envision Yitzchak overlooking Eisav's shortcomings and giving his son unconditional love. Hear HaShem tell Yitzchak, "I will have mercy on your descendants on the merit of the mercy and love that you showed to Eisav."
