People are always watching and evaluating others. Even if we don’t do it consciously, we all do it - especially to Christians! We want to see how they handle the adversity of life - what we do when the going gets tough.
Do they see you react in fear and lash out or do they see you respond with patience and grace. They are attracted to God by the way they see you act, not by any of the things you say. When they witness the peace of God that surpasses all understanding it kind of blows their mind. When they see faith in action, they are watching to see if God shows up. Deep inside they long for what you have. Make sure that it shows.
