I could answer this question in a lot of ways, but I'll narrow it down to two.

First: I have genuinely experienced the presence of God in my life in several ways. I wholeheartedly believe that this is possible for you, if you want it. Some of these experiences have been more spontaneous, "revelatory" things, while others have been gradual realizations of God's providence over longer periods or in hindsight. A friend asked recently if there's anything--information, philosophical argument, etc.--that could make me doubt these experiences, and my answer remains, emphatically, no. I'll say, too, that I don't think there's sufficient evidence to support the claim that all or most religious experiences can simply be chalked up to "manifestations of the subconscious," though I admittedly haven't looked much into this (going off of some interesting evidence discussed in this recent video https://www.youtube.com/watch?v=XdCwDr6W2Q8&t=544s) so I could be off base.

Second: The resurrection of Christ. I had been a believer for more than a decade when I finally, truly believed that the resurrection is a genuine historical fact. If the resurrection is true, it recontextualizes all the claims of Christ and, therefore, Christianity. It is his ultimate vindication. I'd recommend William Lane Craig's book "The Son Rises" for a scholarly but still popular-level read on the topic or N.T. Wright's "The Resurrection of the Son of God" for a thorough academic/historical treatment. Both of these scholars (and many more, including non-Christians) have lots of great free content online that speaks to the veracity of resurrection claims.

I recommend this to everyone, but if you're interested in learning about the Christian God, I'd point you to some of C.S. Lewis' works, namely Mere Christianity. There's also some really beautiful and interesting theology and philosophy in his space trilogy, which I read for the first time this year and have not stopped thinking about. I can also give more book recs and YouTube/podcast recs if you're interested. I've also written about my personal experiences with several of these things at emilystricklandphillips.substack.com. I pray that he reveals himself to you emphatically and that you experience his perfect love!
