We see the final step that the servant took later in chapter 24:
49Now if you will show kindness and faithfulness to my master, tell me; and if not, tell me, so I may know which way to turn.” 50Laban and Bethuel answered, “This is from the Lord; we can say nothing to you one way or the other. 51Here is Rebekah; take her and go and let her become the wife of your master’s son, as the Lord has directed.”
It is not advisable to marry quickly without the consent of the parents. If the parents object to the one that has been chosen, the young people should slow down and do some investigating. The parents may have a good reason for rejecting that person. Even if they determine that they are in God’s will to get married, they should go slowly and let the parents get used to the idea and get to know the one chosen well. If they eventually decide to go ahead with the marriage even though the parents object, they should seek the counsel of wise leaders in the church to help them through the process. In fact, if possible, all engaged couples should have a lengthy period, at least 3 months, preferably 6, of premarital counseling by someone who has been trained – or has the necessary life experience – to do this. If no one is available, there are some good books they could read together as the wedding day approaches.
