Suitable Suitor

I'm mulling over a lot while working on reclaiming the upstairs study, and I would like some help from you. No, not with the work but with the "mulling" part. We've been putting a lot of thought into what constitutes a suitable suitor for a daughter. I'm not talking about your average "let's hang out at a movie or coffee shop date". I'm talking about a real suitor. Other than being a Christian and basic requirements such as that, I want something more concrete on paper. Lately, after listening to a message on CD, I've been giving a lot of thought to the idea that a man must have a vision for his life....a way in which he ministers to the body of Christ or the world...before he can ask a young lady to follow him. Agreeing to marriage, puts a young woman in a very vulnerable position; how can she be asked to follow or submit to someone who doesn't have a clue as to where they are going? Also, a suitor needs to be someone who can lead spiritually....not just someone who is spiritual, but someone who is knowledgeable and able to guide and lead his family without falling prey to heresies big or small. There is a lot more on my mind, but I want to know what's on your mind. I want to know what you think, so I can think about it as well. So, what are some of your thoughts as to what constitutes a suitable suitor?
