Sin is a bit like when toxic waste is spilled into a river: Years ago people thought nothing of polluting streams and rivers with chemical waste and rubbish. It just seemed so unimportant; nothing really to worry about! But today we know that just two or three parts in a million of certain chemicals can seriously damage people’s health, even kill them! Sin is like the pollution in streams: even tiny amounts are deadly because it spreads like a virus. And sin also spreads and passes from one generation to the next. We are all sinful… we are born that way. Sin is something we’ve inherited; it’s been passed on in our genes from one generation to the next right the way back to Adam and Eve!
