Hello, community. Something truly incredible happened to me with Lucifer.
Since the beginning of my journey with magic, I started with Lucifer, and I am still learning since I have a lot to improve. However, I am happy with my constant progress, even if it is slow, haha.
Recently, my mom had a fistula in her intestine, and she had to go quickly to the doctor. She also has anemia (which she’s had for a long time).
The surgery she was going to need was very high-risk.
I was scared, so one night, while I was alone at home, I took the opportunity to use the sigil, some offerings like copal incense, dragon’s blood, and some sweets, along with wine. I also recited his Enn and litany of @C.Kendall
I called upon Lucifer, kindly asking for his help since he is the only one I work with when it comes to magical matters, and I was genuinely terrified that something might happen to my mom.
Apart from inviting him and asking for his help, I offered him something I had already promised him: my blood for the first time. I pricked my finger with a needle (I was quite scared as it was my first time drawing blood, but I wanted to save my mom), and with all my faith in Father Lucifer, I hoped everything would turn out well.
The next day, before they performed the surgery, they did a check-up and some tests just to be sure, and everything came back positive—she was healed. The doctor couldn’t believe it, wondering how everything could turn out fine, and the fistula closed up on its own as if by magic.
When they called me to tell me she was healthy and wouldn’t need surgery, I was incredibly happy and utterly surprised by Lucifer’s capabilities, as I didn’t know he had such power in the realm of healing.
My mom also told me that one day before, she was feeling perfectly fine, but this came out of nowhere, and she could smell the scent of cemetery soil.
I believe someone performed black magic on her. I am considering asking Lucifer for help in returning that spell to the person who wanted to harm my mom—obviously, in exchange for something.
I welcome any recommendations or advice about any deity, spirit, or entity to help return the work to that person, multiplied.
Back to the topic, I highly recommend Lucifer to all witches and warlocks, as he is a very powerful and kind god as long as he is treated with respect. 

Sorry if some things are unclear, but I don’t speak English—my language is Spanish.
