Avraham asked Hashem that Yishmael should be the one to carry on the legacy of the chosen nation. Hashem explained that Yitzchak represents a life based on Kabolas Ol, while Yishmael lived a life of reason.
In order to answer this question we must understand the contrast between the life of Yishmael and Yitzchak. Now that we have some understanding, Hashem was making it very clear to Avraham that the true Jewish Nachas can be had specifically from such a child whose birth, and his entire life, right away from when he is born and onwards, is in a G-dly way. And when he is a child of only eight days, this means right when there is the first chance to do so, we connect him with Hashem with an everlasting covenant, an everlasting connection. Although he still doesn’t understand anything, and we are still unable to ask him (for approval). By such a child his Judaism will be not only according to understanding, but with Mesiras Nefesh, and we will have from him the true Jewish Nachas.

Lessons in Chinuch
There are people who think that when educating children, it is enough to wait until they grow up and can conduct themselves with understanding. However, the Torah teaches us that from birth onwards, a child should be connected to Hashem in a G-dly way, not just through intellect but with Mesiras Nefesh. This connection is everlasting and not dependent on understanding or approval.
Everlasting Connection
Hashem said to Avrohom that the true Jewish Nachas can be had specifically from such a child whose birth, and his entire life, right away from when he is born and onwards, is in a G-dly way. And when he is a child of only eight days, this means right when there is the first chance to do so, we connect him with Hashem with an everlasting covenant, an everlasting connection. Although he still doesn’t understand anything, and we are still unable to ask him (for approval). By such a child his Judaism will be not only according to understanding, but with Mesiras Nefesh, and we will have from him the true Jewish Nachas.
