Your father Abraham rejoiced to see my day: and he saw it, and was glad.

Abraham, your father, rejoiced that he might see my day, my entrance into this world, my incarnation, my birth, my manifestation in Israel, my death and passion. (St. Iren us, Origen, St. Cyril)
He waited with impatience for the deliverance of the whole world. He saw it, and was glad. He saw it in spirit, for God revealed it to him. He saw it approaching in the birth of his son Isaac, and in the miraculous deliverance of his dear son, when he was commanded to offer him in sacrifice to the Lord. The vivacity of his faith made him, as it were, present at the time of my birth, though then so far off. (St. Chrysostom, Leont., Theophylactus, Euthymius)
It is not unlikely that this patriarch, and the others who were with him, detained in limbo, were apprised of the incarnation and coming of the Messias, which would fill them with an effusion of inexpressible joy. (St. Chrysostom)
Christ here teaches us two things. 1. That he was before Abraham. 2. That the Jews were not true sons of Abraham, now treating so rudely him, who, even before his coming, had given the patriarch so much joy. (Calmet)
