Acts 28:16-31

After Paul arrived in Rome, he met with some of the Jewish leaders to discuss his situation. Paul told them about the charges brought against him and maintained that he had been falsely accused. The Jewish leaders had not had any word from Jerusalem regarding Paul, but were curious to hear His views on the Christian beliefs. Paul preached to a large crowd about Jesus using Hebrew scripture to make his case. Some of the people listening believed, but some did not. Paul then spent two years preaching from his home to anyone who would come and listen.

When someone comes to you wanting to know about Jesus, just tell them what you know and let the Holy Spirit take it from there. There is no perfect formula or surefire string of words to put together to make a person believe. Each person needs to weigh the information they receive and decide what they're going to believe. Pray for guidance when you are speaking; pray for God to open up the heart of the person listening and then let God do the rest.
