Today, years after conversion and our marriage, she'd never do that. But even for those Christians who still do that, I prefer to let them come in "immodest", than to not come in at all.
I agree. As they mature they will learn better and do better. OTOH, maybe the ones, the males in particular, who have such a problem with these ladies need to check themselves and examine why they are looking in the first place. Seems to me there are still a lot of church folk more concerned with what others are wearing than they are listening to the pastor.
Myself, I would much rather be in a sanctuary with a couple of hundred ill dressed sinners coming to know the Lord and His saving grace than I would a bunch of well dressed busybodies.
