My aunt is dangerously ill. They found covid in her system, though she also has another lung problem. She is elderly but has been quite fit and appears like a younger person so this is a shock. I would say to her too.
Pray she will know and feel the presence of Jesus. That she will give her heart to Him and truly know His forgiveness and freedom .
Lord heal her in every way. Let her stay here on earth for a long time yet.
