My brother, if you have a friend that knows how your feel about your faith, they can see what kind of person you are by your actions and deeds.
There is no compulsion in Islam.
Your character and the advice that you offer when asked, will let anyone that you communicate with know. That you, are balanced and unbiased and have goodness in you.
You can not make a person change what they believe. Religion has to make sense and you must feel it in your soul. Islam is a way of life, not what you wear or how much Arabia you speak.
Lead by example.
