I once found myself translating during an interview/test of a potential convert to Torah Judaism. What one believes in is crucial to be accepted as a גר צדק Ger Tzedek, Righteous Convert. Evangelical Christians can never convert to Judaism, and if they lie about their beliefs, their conversions are null and void:
Question: "What is an Evangelical Christian?"
Answer: To begin, let’s break down the two words. The term "Christian" essentially means "little Christ." "Christian" is the term given to followers of Jesus Christ in the first century A.D. (Acts 11:26). The term "evangelical" comes from the Greek word that means "good news." Evangelism is sharing the good news of the salvation that is available through Jesus Christ. An evangelical, then, is a person dedicated to promoting the good news about Jesus Christ. Combined, the description "evangelical Christian" is intended to indicate a believer in Jesus Christ who is faithful in sharing and promoting the good news.
Their beliefs are the antithesis of Judaism, plain and simple. There's no way of getting around it.
