That's so not true....they all care....saints, and non-saints, alike.
The saints gather to pray along with us at the Divine Liturgy. They perform miracles to heal us, pray to God to help and forgive us. Countless saints have appeared after their deaths to come to our aid. Read up on St. Nektarios. http://www.johnsanidopoulos.com/2009/11/unbelievable-yet-true-miracle-of-saint.html
Even our deceased family members care. Hasn't anyone experienced seeing their "dead" in time of crisis in a dream? I know I have. When I'm not even thinking about them....because I'm so stressed and there are major life issues weighing me down..... my godfather shows up in my dreams to calm me down and give me some perspective. Yes, you could say it's coincidence.....however, on that same night my mother, who was also stressed about the same thing I was....also had seen her brother in her dreams. Now THAT is a coincidence.
I have to believe he sees us and is concerned and therefore, manifests in our dreams. I know we are advised not to believe our dreams, and sometimes they truly are not from God and only serve to scare and cause insecurity in us. However, my godfather, when he does show up, rarely speaks. He works, he sits, he doesn't smile or joke....but, every once in a while he will utter a sentence. This sentence will confound us and we won't know what it means, until days later, something happens....and the light-bulb goes off.
My mom is really devout....and one night in her dream a recently dead parishioner "visited". In her dream the woman asked my mom to go to church on Saturday evening and to pray and light a candle for her. She asked me to take her to Vespers so she could pray for this lady. When we entered the Narthex a man was at the candle stand. He was buying candles....and seeing my mother, he turned and gave her one....without asking if she wanted one or not.
We had arrived early for Vespers, but, there was already a service in progress. It turned out that the lady's children were having a memorial service for her. My mom held the lit candle during the service and prayed for the peaceful repose of this woman.
I have more examples like these. They can't be just mere coincidence.
