I was recently encouraged by someone at church who has been counseling me in my search for my wife to write down all the attributes I'm looking for and commit them to God. I don't believe this will be the final list, but I do think this covers a lot of what is required. The characteristics in the list below aren't a matter of personal preference, they're non-negotiable. This isn't to say I don't have work to do in the following categories, but I know that my wife will be:
Willing to serve others first
Has a good, loving relationship with her family
A hard worker
Of noble character
If anyone reading this has additional suggestions based on Biblical principles or life experiences, please comment or contact me in some fashion.
