I've used this story to illustrate this topic a number of time = Daddy/husband comes home to wife and kids and has with him a young small poisonous snake. He tells wife and kids we will love him, give him warm place to sleep and feed him and then he will love us! Wife knows what the snake is and so do kids. Essentially wife screams at idiot and yells at him GET THAT EVIL THING OUT OF OUR HOME IT WILL BITE US AND COULD KILL THE CHILDREN!!! Husband calms wife and says o no no no he will love us we just have to show love to him. Wife being much smarter than her idiot husband orders kids to their room and pack clothing and toys and tells them WE ARE LEAVING AND WILL GO LIVE IN SAFETY and that's what they do". The moral of this sermon is some people WANT to bring in evil believing if they are just nice to it then all will be well. And demonstrably no. It will not be ok.
