This is just my experience OP.
Similar background, raised in the church, grew up, fell away, redirected back a while ago. I'm a firm believer that unless people experience or encounter God in some way that makes a mark in their life they will fall away as one can only go to a building so often singing hymns, listening, socializing, etc. before their heart wanders as the core of the individual doesn't experience what the bible says they will or they believe they should.
Problem is most times I find people are waiting on God where in a twist, God is waiting on us. You're always as close as you want to be, is my motto. In college I got more desperate and instead of just reading, I would meditate on the word and many times just spend a few hours alone listening to worship music pursuing his presence. Soon I experienced his presence in what I can only explain as a lightning fire sensation and would stay with me from that day on every time the holy spirit's presence manifested in me when pursuing him, or when it was pursuing me. I would receive dreams where it was evident he was speaking to me through them, even had one that replayed a scene that occurred through the day earlier showing me the person I talked to was an angel.
Eventually that in itself wasn't enough. I fasted on two separate occasions during two years for over 30 days on just water, broth, coffee and tea; no food. I experienced visions and short visitations over that time. Most would pass that off as malnutrition but I wasn't working out or doing any physical labor of the sort during this time. My job is mostly occupied in a cubicle in front of a computer; I would meditate during my time at lunch, come home, pray, meditate, read and then sleep. I only encountered and experienced such during alone time by sitting down and meditating on Christ. Joy, peace, love, all of that was experienced in ways I cannot explain. Struggles were cast aside and stayed away for virtually the rest of the year as his peace stayed on me.
I've fasted before in my youth, but my heart wasn't in the right place for fasting. That time, it was an act of desperation, wanting to be closer to him at whatever the cost. I didn't have weight loss, or food concern in my mind and was focused on him 100% which was key. I didn't fast for the sake of fasting and just go about my day; I pursued him tirelessly, daily. Many people make it a yearly routine. Personally, I believe your heart has to be in the right place as it's about relationship with him, not routine.
I have since then yet to do so again, which was roughly 4 years ago but it changed me permanently from that day on. Aside from that, I'm a firm believer as in the days of old, God speaks to us differently in many ways. Some times it's through other people regardless of their beliefs, age, gender, etc. "My sheep hear my voice" sticks with me. Doesn't mean he speaks audibly although many claim to have heard him in such. To me it means he speaks to us in a way that we recognize his voice in everything when he does so, so long you're alert, listening. For me it's through other people; many times through dreams which are mostly symbolic in nature, and circumstances.
Where I'm going with this is if I never pursued God those years ago I would had fallen back aside again. Even if my actions today are not as much as back then, my heart, soul and thoughts are daily on him, listening, looking, learning. We should be like a sponge, allowing the Holy Spirit to teach us daily, humbling us, growing and slowly, very slowly it seems, learning from our foolishness.
Those experiences during that time which to me seemed like supernatural encounters are my anchors in this life where no man will sway me only because I've experienced them when pursuing the father in hunger. When I struggle through sin and life in general, I can look back and remember those times with things I've seen, experienced and continue to do so knowing it was real. Those days of fasting and after were the best times spiritually of my life being at peace.
It comes down to how you approach him in your heart's intent. Question is, how hungry are you and what are you going to do about it? How far will you go? Are you willing to give up? These are the things you need to ask yourself.
I am a firm believer in very few make it very far experiencing what many like to claim only existed back in the bible days with the supernatural experiences only because very few are willing to pay the cost.
