And in their footsteps We sent Jesus the son of Mary, confirming the Law that had come before him: We sent him the Gospel: therein was guidance and light, and confirmation of the Law that had come before him: a guidance and an admonition to those who fear Allah.
In their footsteps means in the footsteps of the prophets who submitted,
mentioned in v. 44 (R, Z). In the present verse both Jesus and the Gospel he
brings are separately described as confirming the Torah. Jesus is also described
as confirming the Torah in 3:50 and 61:6, as is John the Baptist in 3:39. That
Jesus “confirms the Torah” means that he upholds the validity of all Torah
rulings not specifically abrogated by the Gospel (Ṭ); see also 3:50, where Jesus
comes to make lawful unto the Israelites part of that which was forbidden to
them. The Gospel here, like the Torah in v. 44, is described as containing a
guidance and a light. The Quran is also described as a light in v. 15; 7:157; 64:8.
