We are made in the imago dei. Every human being is made in the image of God. This means a great many things. Specifically, it does mean we are all connected. As God is 3 in 1, we are all connected in a great way. There is a solidarity to the image of God we are all connected within.
Think of this!
This means every interaction, no matter how passing or intentional, has an impact. Every smile, hug, and conversation has an impact. Every relationship, no matter how intimate or shallow, has an impact. You may never see a person again, but in that second your smile could impact the rest of their hour or day. It means even your small acquaintance has an impact.
Think of how crazy it is that you, a human being, have the capacity to impact another human being.
What impact will you have?
