Whenever we talk with people of other faiths ( especially with people who are not Christians), we ought to take the attitude of Paul and invite them to “taste and see” whether the claims of Christianity are objectively true or whether they are simply fanciful wishes we’ve decided to codify and believe.
Christianity is the only faith that has any objective evidence to show that it’s clams are not just wishful thinking but something we can, and should, place our hopes in the future in through something called “faith”.
Everyone has faith in something, the only question is whether or not that something is worth having faith in.
