1Now it came about, when Isaac was old and his eyes were too dim to see, that he called his older son Esau and said to him, “My son.” And he said to him, “Here I am.” 2Isaac said, “Behold now, I am old and I do not know the day of my death. 3“Now then, please take your gear, your quiver and your bow, and go out to the field and hunt game for me; 4and prepare a savory dish for me such as I love, and bring it to me that I may eat, so that my soul may bless you before I die.”
After all that Esau had done (and we didn’t even go into his choice of wives yesterday), Isaac still loved his son, and wanted to give him the blessing of the firstborn before he died. It is not unlike the grace that God shows us constantly. After all we’ve done, He still loves us, He still forgives us, He still wants to bless us, if we will do His will.
