I think a fault of many people today, especially Christians sometimes is how we are so quick to 'pre-judge' a person.
The only person who can make an accurate evaluation is Jesus. He's God after all, but for the majority of people including myself, is we have a higher estimation of ourselves and we falter in our perceptions.
I'll never forget the story of a single Christian mother with two kids playing softball in the park.
A huge, clearly homeless man approached her quietly and asked if he can help fetch the balls hit by the woman's daughters.
Now here you can make your presuppositions. You can run, decline, or let God really tell you what to do. If I was this woman's husband, I would say, "Move the kids out and get in the car. You're alone, and this sounds really like it could be bad."
God told this mother, "Reach out." (Mind you, God's pretty spontaneous and fresh and will always give the right answer and sometimes it goes against common sense, and it's NEVER the same answer,way sometimes).
So this mother let's the stranger fetch the ball for a while. Then, the stranger asked, "Can I hit the ball?"
Ok, fetching a ball is one thing, but turning over a bat to a stranger as a single mother with your children is now really stepping out by faith. The woman prayed, and sense God wanted her to do it - even thought it went against common sense, but she felt compelled to let the man hit the ball.
The mother nervously step up to pitch the ball, and the stranger connects.
She says it went two hundred feet. She looked at the ball traveling and back at the stranger. The man smiled and asked for another ball to be pitched.
This one sails like a bat out of hell, and travels three hundred feet.
The girls are all excited - it's like a show!
The hits keeps coming and the stranger smashes each pitch like Paul Bunyan: Three hundred feet. Four hundred feet. Even one smash-hit sails like it was from a movie from the Field of Dreams or the Natural. It was surreal.
The stranger launched every ball literally out of the park as the girls runs to find the balls. Each time the mother whispers, "Amazing."
It was like a literal private home-run derby. Finally, the stranger drops the bats, smiles and softly says, "Thank you."
The woman watches him walk away and rushes to catch him, "Where did you learn to hit the ball like that?"
The stranger looks to the ground and softly says, "The Atlanta Braves."
Yes, THAT Atlanta Braves, - the professional baseball team.
You never know soemeone's story, or where they came from. Just because they act, say or look a certain way - remember there is a story to them. Maybe when you find out you don't look at the book cover, but read the book.
