What can I do to help my parents stop worrying about my faith? [Spirituality & Religion]

I was raised atheist, by atheist parents. Recently, fortunately, I've come to accept Jesus as my Lord and Saviour. My parents do not like that. They are geniunely afraid I'll end up in a cult because of my belief in God.

What can I do to make it easier for them? I don't want to compromise my Christian values (even though it's not like they cause conflicts with their lifestyle that much anyway), but I don't want them to worry so much about me, there's simply no need for it.

I've been trying to act lovingly and acceptingly towards them even when we argue about faith, which seems to work. Any further advice?

Similar personal experiences are also welcome.
