I can believe in God in general, but I get stuck on Jesus specifically: the resurrection, the claims, all of it. How do I work through that?

“He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we hid as it were our faces from him; he was despised, and we esteemed him not.”

This belongs to the last of Isaiah's servant songs, written centuries before the events Christians read into it, and it describes a figure whose suffering is rejected and misread by everyone watching. Whatever you conclude about the connection, the portrait is not what an invented messiah would look like. A humiliated servant was the opposite of what that nation expected and wanted.

“Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. And Thomas answered and said unto him, My Lord and my God.”

Thomas has refused the other disciples' testimony and demanded physical evidence, and he holds that position for a week. When Jesus appears he does not shame him; he offers precisely the evidence Thomas asked for. The gospel writer kept the whole embarrassing episode in, demand included. The earliest church clearly did not regard this kind of doubt as unmentionable.
