Have you ever had a moment where you could tell someone else was a Christian? I was at the bank one day meeting with a financial advisor, and part way though our conversation I said, “You’re a Christian aren’t you.” And she said, “Yeah, how could you tell?” Her temperament, her joy, her conduct – everything about the way she was acting just screamed ‘Jesus.’
Paul says in Galatians 6:10 that as we have the opportunity, we’re to do good to all people. In every way we’re to act like Christ what would Jesus do. Paul goes on to say that “we’re to do good to all people, especially to those who belong to the family of believers.”
You see, while I might be able to pick out the odd Christian based on the way they interact with others in their workplace or neighbourhood, the most powerful witness is actually how you interact with other Christians. We’re part of the same family.
When you walk into someone’ house you can very quickly get a sense of your welcome based on how the members of the family treat one another.
And when you look past your brothers and sisters shortcomings and choose to love them, Jesus says this unity testifies that God sent His son to the world. Why? Because this kind of doing good is from out of this word.
