I like this one, because it's not directed just at the girls. It really irritates me when girls are the sole targets of 'modesty training' arguments. Boys need to be taught not to be pigs, perhaps even more than girls need to be swathed in potato sacks and ugly shoes.
Isaiah 66:9.. God's promise. My Bible says the reverse: "Do I bring to the moment of birth and not give delivery?" says your God. The pain comes first, as if it must come first and not so much that birth or something good, always follows pain. A message of hope either way but the painted sign is a bit softer and more hopeful. Fitting.
I will not cause pain without allowing something new to be born. -Isaiah 66:9
