Some people think they are stubborn and resistant pieces of cement that God can hardly wait to break… Rubbish. Everyone born again by the Spirit has been born of a new nature… Giving my dog a whack to her backside might send her a message, but she’s a dog, and we don’t speak the same language, we don’t have the same nature, and I don’t live in her! I may get the behavior I want (and the lowered head and tail between the legs as well), but so what? Do I get any glory for what I’ve done? Any worship or praise? Is she glad and thankful for the whack? No! She just wants to do whatever it takes to avoid it in the future. Is that how God treats us – like His special pack of dogs? That’s a dog’s life, but it’s not mine, and it’s not yours.

Yea, even my dog gets treated better than the way some people portray God’s treatment of His people. And I think my dog also has a better understanding of grace.
