i have been a member of charismatic churches.
i know of more miracles happening in the orthodox churches.
we don't like to focus on the miracles, though, as the biggest miracle of all is God coming down to us in a human form and taking on our nature in order to bring us closer to God's divine nature.
but there are a few miracles that were so public that we talk about them:
the appearance of the virgin mary in egypt.
God allowed her to appear to bring comfort to people.
as the muslims also consider her to be a great follower of God, then many of them also saw and believed.
i have personally met people who were there (incuding a muslim) who saw this and it brought them closer to God.
may God be glorified forever!
