I was skeptical all the time. Converts and cradle Christians alike used to tell me the many wonders of Jesus. I used to say " It’s the medical science in action, not your Jesus’ miracle". In non medical cases , my thought was " It was just a coincidence".
Even when I finally decided to convert, there still were remnants of my doubts and skepticism. I decided to convert because nothing gave me the inner peace I was so starving for. Meditations did but it wasn’t the type of peace I longed for. I wanted to feel connected to something as I felt empty. When I converted, to be honest, it was a part of “experiment” to see how I would fare.
I used to do prayers to Jesus hoping for a “miracle” all the time. But the intended miracle never happened until I actually resolved that this way was futile and that I should either entirely give it up or fully acknowledge Jesus as my Divine friend. I had no patience, I realized. If Jesus were to answer immediately to what one asked for, think of it - we would all be lazy. We would take things for granted. We would become greedy to ask for more.
The realization alone opened up my heart wider. God is not an experiment. How stupid of me to take Him lightly!!! And that’s how I firmly established a foundation within me. Those “miracles” came in the form of my changed view of life and people around me. Yes, it truly was a wonder.
Now, I pray for others more than I do for myself; I don’t hold grudge against anyone which I used to for a long time, I forgive and forget, I resort to prayers when things get out (and beyond) my control instead of cussing and cursing and so on. The other miracles perhaps, I shouldn’t miss saying is being healed from my headache that has nagged me for more than a decade. I forgot the exact diagnosis but it caused me such a repetitive episodes of headaches, I hated life with all my heart. I just wanted to die. That’s it. It wasn’t a prayer immediately answered though. Nevertheless, I’m surprised that I don’t have to take painkillers anymore. They lie on the shelves untouched since several months.
About Jesus appearing in dreams of skeptics , I don’t know why Jesus appeared in mine. I hadn’t even asked Him to prove Himself (although, I was just praying to Him without any intentions).
But what I can tell you is that you CAN’T CHALLENGE GOD. He isn’t like your average neighbour next door with whom you can contest, compete or challenge. Your question " why hasn’t he come to me in my dreams, if he’s real?" is in a way a challenge to the divine being. We can question Him but not while doubting His existence. But then, it is exactly because we doubt His existence, He doesn’t (or may not) come in our lives. He won’t force you to accept Him.
