I would simply ask, “and they know it is Jesus, HOW? Who knows what He looks like? Just like the Mary “apparitions”.
Have you ever had a dream where you “knew” you could fly?
Have you ever had a dream where you “knew” the person you were talking to was your deceased mother, but the figure in your dream looked nothing like her? But, your heart leapt at being able to talk with her and you woke up feeling wonderful?
God works in mysterious ways. Don’t try to anchor Him to our pedestrian intellect.
>> I would simply ask, “and they know it is Jesus, HOW?<<
Are we sure it matters? Once again I would say if it leads to a true conversion with acceptance of Jesus as Lord and Savior alone with veneration of Him alone we shouldn’t dismiss it out of hand without knowing the result in that persons life.
>> Just like the Mary “apparitions”.<<
I would say there is a huge difference there. Veneration of Mary or someone other than Jesus is not of God.
