In many areas I am willing to give and take when it comes to young men to whom I will give my blessing in pursuit of my daughter's hand. I am willing to abide a short man, a poor man, an unattractive man, even a man who is not a Texan (Lord, forgive me). However, I cannot give my consent to a man who is not a follower of Christ.
Whatever words we choose to use, it is clear that a young man must be ready to represent his family before God (as a priest), represent God before his family (as a prophet), meet the needs of those in his household (as a provider), and place himself between his family and all who would do them harm (as a protector).
A young man who is worthy of a wife will have a clear understanding of the covenantal nature of marriage. He will also have a healthy apprehension when he thinks about the magnitude of his responsibility should he assume the role of husband and father. He must know the weight he is taking on his shoulders and be willing to accept it. He must be a man who is willing to endure hardship for the sake of his family should he be called upon to do so.
