The last part, or often actually the first part, about being approachable is to hear their story. Give them time to share where their journey of faith has led them so far. And then you can tailor your story and God's story to meet them where they are at in that journey. That doesn't mean you leave things out but it may mean you focus on certain aspects more than others.
Just like you wouldn't teach a 2nd grader mathematics the same way you would teach a high schooler, and often you need a series of sessions to teach it well. A one size fits all model of gospel presentations is not always appropriate. There are still essentials that need to happen but hopefully if you have a loving relationship with them, it can happen over multiple conversations.
I think of Paul at the areopagus where he started with where the Atheneans were at. He observed their attempts to reach out to God with idols. Reasoned with them in the markets every day. Went to the place where they had their communal conversations and debates. Spoke in words and phrases they could relate to. And finally at the very end, made a call for repentance, mentioning judgement and speaking of Jesus rising from the dead. Those that the spirit worked in wanted to hear more and followed him. Others mocked him but he did not focus on them.
