I can certainly understand the preparedness statement, because it makes sense and in many cases it is required.
Ultimately a successful couple is comprised of two individuals. They may become one in unity under marriage, but they are still two individuals and should both be individually prepared in their own way.
Whether or not God is choosing circumstances for us in that regard, we'd still be wise to utilise (and enjoy) that freedom from commitment to work on ourselves and better prepare for life in general, but also for life in marriage and what we can and do bring to the table.
I know for myself I feel God placing great emphasis on me to be better able to fellowship with my future spouse. That means a greater foundational understanding of Scripture and what it means to be Christian, a depth of knowledge that can facilitate edifying conversation, and an overall wisdom, grounded in Scripture, that will help keep our union fruitful, edifying and stable for the rest of our lives.
So that's what I'm working on at the moment, both as an individual for my own benefit, but also being conscious that getting my own house in order means I'm a better host for a potential spouse when the time comes too.
As far as the speakers go, it's frustrating sometimes when people like that think because they've reached that point that they're an authority, but ultimately reaching a destination doesn't mean they understand the journey, and a journey is anything but linear. I am sure they offer some valuable insight, though.
There are some things that the single men will, on average, struggle with more than the ladies. We've seen one example paraded and wrongly defended here, and it's sad how ready some folks are to try and defend the indefensible, so I can understand why in that setting they would be trying to address certain themes.
I'm sorry it was a negative experience, though, and I do agree that it's a great environment and opportunity to meet like-minded people that are also seeking the same thing. I hope they recognise that and can balance that aspect as well.
