I agree. We cannot learn about God without the Lord Jesus Christ's. We need Jesus Christ to enlighten us to gain any insight into God. However, a person may be being helped by Jesus Christ to understabd some truths about God without knowing the name Jesus Christ or realising that Jesus Christ is enlightening their understanding.
John says -
Jhn 1:4 In [the Word] was life; and the life was the light of men.
Jhn 1:5 And the light shineth in darkness; and the darkness comprehended it not.
Jhn 1:8 [John the Baptist] was not that Light, but
was sent to bear witness of that Light.
Jhn 1:9 That was the true Light, which lights
every man that comes into the world.
Jhn 1:10 He was in the world, and the world was made by him, and
the world knew him not.
Jesus Christ is the life which is the light of men, who lights every man that comes into the world, but the world nevertheless did not recognise Him when He came.
