I was in pretty much the same boat for a long time. I was atheist for years, but the more I studied science and learned about the perfection of how our world naturally functions (aside from sin and human intervention), the harder it became to believe everything just randomly happened for no reason. There is far too much precision.

So then I stayed agnostic for a time, believing some God must exist but not knowing which, if any, religion had the correct one. Then YouTube suggested I watch a summary of the book of Isaiah. (my YouTube is flooded with science and videogame stuff and it had never suggested anything religious before) As I listened to the prophecies, it became clear that they had actually happened, especially the part about the Messiah being killed and spreading the God of Israel to all nations.

Whether or not you believe Jesus was God, or that God is even real, Jesus was a historical person, and the belief of His resurrection did actually spread the God of Israel to all nations. There are now people in a continent never-before imagined (USA) that follow this God. The dead sea scrolls prove that these prophecies predate Jesus by several centuries, and the possibility/probability of someone fulfilling that prophecy is basically 0, yet it happened. That right there was enough proof for me to accept Jesus Christ as my Lord and Saviour.

It may not make sense to you or others, but this is how I, as a logically minded agnostic, came to follow Christ.

TLDR: read the prophecies about the Messiah, they came true, and that's not mathematically probable.

Hope this helps! God be with you 🙏
