A young executive was traveling down a neighborhood street.He was watching for kids rushing out from between parked cars and slowed down when he thought he saw something.As his car passed,no children appeared.Instead,a brick smashed into his door! He slammed on the brakes(make his car stop).The angry driver then jumped out of the car, caught the nearest kid and pushed him up against a parked car,shouting,“What was that all about and who are you?”

The young boy was apologetic.“Please,Mister...Please,I’m sorry…I didn’t know what else to do.I threw the brick because no one else would stop…”

With tears dripping down his face,the youth pointed to a spot just around a parked car.“It’s my brother,”he said.“He fell out of his wheelchair and I can’t lift him up.”

Now sobbing(crying silently),the boy asked the executive,“Would you please help me get him back into his wheelchair? He’s hurt and he’s too heavy for me.’’

Moved beyond words,the driver tried to swallow the rapidly swelling lump in his throat.He hurriedly lifted the boy back into the wheelchair,then took out his fancy handkerchief and dabbed(a light touch) at the fresh scrapes and cuts.A quick look told him everything was going to be okay.“Thank you and may God bless you.”the grateful child told the stranger.Shaken up for words,the man simply watched the little boy push his wheelchair—bound brother down the sidewalk toward their home.

God whispers in our souls and speaks to our hearts.Sometimes when we don’t have time to listen,he has to throw a brick at us.Don’t go through life so fast that someone has to throw a brick at you to get your attention!
