How do you minister to atheists ?

I am not trying to offend people whatsoever but at my church we are called to share our faith with people and minister to our peers. However I have people in my family that are atheists. I try to tell them of God’s love but they don’t seem to care. What can I do ?

Edit. Like I said I am not meaning to be offensive I am called to share my faith. I want my family to go to heaven and take the steps to know God . 😊
