God said,

I have been with you wherever you went

Regarding Jesus, God said,

I will be a father to him,
and he shall be a son to me

The angel Gabriel said to Mary,

Do not be afraid

for

nothing will be impossible for God

to which Mary replied,

Let it be done to me according to your word

May I have the faith of Mary
