In your opinion what causes christians to believe in Jesus

[Sheldon]

It isn't shopping around. The word has two different senses. Can you not just state which sense you are talking about? 

My argument is that only one sense exists within Christianity—that of trust. The other senses are as irrelevant as it is to point out that bank also means the edge of a river when I'm trying to deposit money. These might as well be different words, so there's no reason to acknowledge them as having equal merit.

Except this ignores the fact that it is you who was subjectively shopping around for a definition, as this is at odds with how religious faith is defined, and yet you falsely accused me of shopping around for a definition, when I simply quoted, and linked, the Oxford English dictionary.

The word trust does not appear in the Oxford English definition of RELIGIOUS faith, only in the primary definition. 

faith
Definitions from Oxford Languages · 
noun
1. complete trust or confidence in someone or something.
2. strong belief in the doctrines of a religion, based on spiritual conviction rather than proof.

You have pointedly failed to address this fact, while lying that I was the one "shopping around" for a definition. 

The only response I got was some vague facile claim, to seek out the Greek etymology of the word. Again this suggest it is you who is deviating from common usage, not me.
