Pascal's Pensees
Christian books
I have a couple books you may like depending on your circumstance. Answering Atheism by Trent Horn if you're looking for a more accessible look at classical arguments for theism. If you have a little background in philosophy you might prefer Aquinas: A beginner's Guide and The Last Superstition by Edward Feser.
In any case I don't think any one book will convince you to believe in God. At least for me it was a very gradual process and I couldn't even tell you when I started to believe. I just had an interest in theology and because I'm always reading two or three books at a time I made sure at least one of them was related to theology. I think the best way to become a genuine Christian is to just pretend to be one, try it on for size and see how you like it. You may wake up one day to the realization that you actually are one.
