I've never understood this comparison... It's a heck of a lot easier to follow the Lord than it is to follow another flawed, sinful, and prideful human. Yes, essentially wives are obeying the Lord by following their husbands, but that doesn't make it easy. God is clear, concise, and consistent, most men are not. I think that is where the "complaints" stem from.
What you said is true, but here's another angle. Yes, any Husband is flawed and sinful, but so are we. We can say "yeah Jesus followed but He was following a sinless God." But the rebuttal is "yes, but He was sinless too. We're not. He still followed"
Submitting and following isn't easy. Neither is, say, dying for the Gospel. But we may be called to the latter. Why should we think we get an exemption from the former?
Besides, we've got it easy. We get to
choose the man we submit to and follow. Until a handful of centuries ago, that wasn't the case. Your parents marched you out to meet a man and told you "your his now." When you think about the fact that the New Testament command to serve your Husband as dutifully as you would serve Christ was given to women who had no say in who their husband was,
and yet they were still expected to follow that command...
...It makes you realize, "serving a man who
you selected personally, giving yourself to a man you chose instead of one who was chosen for you, isn't so hard after all."
Submitting isn't easy, just as you said. And yes, the man you are submitting to will screw up, every day. But the only way to be the bride of a perfect man is to become Catholic and be a nun.
