Some of the more overt instances with my God.
I've seen God working in my life for many years. One of my earliest such memories was when I was around 6 or 7, the late 70's. Mom and I were living on our own, but she had been dating a guy who would later become my stepfather. She was in the bathroom taking a bath and I was entertaining myself with my toys. Suddenly, she flew out of the bathroom, threw on clothes and ran out the door, leaving me there alone, a bit surprised, and more than a little confused. Found out later that she had a vision that the boyfriend was in trouble and that she needed to get him right away. In short, he was a city over running from people trying to kill him. My mother had no clue he was there at the time and showed up in the alley where he was hiding, saving his life. He later also became a believer.
When I was around 12 or 13, I had a serious issue with scoliosis. I had even seen the doctor a few times because they planned to put some rod down my back to correct it. Out of the blue, my pastor had a visiting 'faith healer' come in and talk and asked if anyone wanted prayer. I asked for prayer for both my back and an issue with my eyes. The scoliosis healed immediately. my spine cracked and straightened immediately, in front of well over a hundred people, but the eye issue remained. Had no clue why, but later that same issue stopped me from signing up for the job in the Army, diverting me to another job, where I met my wife of now over 20 years.
More recently, in 2019, I found myself having to pay around $3,700 in taxes. I had the money, but it was really going to hurt. In the same timeframe, I received a letter from the state of Iowa, letting me know I had unclaimed money. I went to their website and found it was a hefty sum (for me). I then checked to see if my wife had any money unclaimed as well. She did. Between the two of us, the total we received was within a few dollars of my tax bill.
My oldest son, an atheist like you, moved out of our house almost 10 years ago, when he was around 16, an angry teen and new father. He swore for years that he wouldn't have anything to do with us or God at any point, ever. He's spent years drinking himself into oblivion and rage quitting anger management sessions. Lately, I've been praying that God do somethign in his life, there were specifics but I'm not going into that at the moment. Around 12 days ago, he reached out for us for help, completely out of the blue. I drive back to Iowa from Texas last weekend and picked him up. As we speak, he's sitting in a faith-based rehab center.
Those were some of the more overt instances, but in my life the Lord has provided for me in many ways. Numerous times in my life, I'd suddenly come into a few extra hundred or thousand dollars, only to be followed up shortly with some unexpected expense of a similar amount. Other times, an expense would come up where I saw no way in the budget to pay, but I'd make it through somehow and end up on the other side wondering how that happened. And this has become such a common occurance, that now when I get 'extra' money, I hang onto it and wonder what expense is heading my way.
So yea, I do believe in God and I do talk to Him and He does answer prayers. This is a relationship we have and He is in charge. He's not a genie, He's a Father. Sometimes He tells us no or provides for us in ways we don't expect. He does allow trials and troubles in our lives and has never promised us wealth or health in this life.
