Possible Demographic Choices
(1) racial or ethnic differences- how might an evangelist approach an atheist?
(2) language barriers and country of origin differences
(3) different social and economic circles and values
(4) age differences-
Older or younger; maybe those millennials aren't really as "entitled" as you surmised
(5) occupational differences-
Can a carpenter connect with a chemical engineer or a lawyer with a landscaper?
(5) Physical differences-
Do we tend to avoid people with noticeable physical differences? skinny or heavy, tattooed or not, wheel chair restricted or an athlete?The list of opportunities is as endless as they number of people in our universe. Just locate your complimentary groups and start saying hello. I think even these little acts of acknowledgement and kindness can “count” as serving as God’s proxies in the world.
