I'm agnostic who is in a religiously conflicted bind. Would appreciate any advice from all sides.?

Christianity is all about believing in what Jesus did to save us from our sins. The Jewish scriptures are 100% necessary to understanding just who Jesus is and how he fulfilled prophecies. Why don't you sit down with a copy of the New Testament and read all of Matthew's gospel, in one sitting? Matthew refers a lot to various Hebrew prophecies that Jesus fulfilled. Just pray about what you read and then wait on God, expecting direction.
