Some preachers seem embarrassed by this passage, that it would be this superfluous love story in the middle of such a serious theological work, and so the labour hard to imagine that this text is some sort of allegory for evangelism - and such it might be! However, it is first and foremost the story of Abraham securing a wife for his son. So before we get into any more fanciful interpretation, let’s not despise this passage as it speaks of marriage. As John Calvin writes in his commentary on this text, it is precisely because we do not hold marriage in honour, that Moses would insist on giving us a detailed picture of the marriage of Issac.
Now when we say this is a text about marriage, and an important text about marriage, and we can take some principles from this text without getting absorbed into the details and say, this is the key to finding a wife - first, get a really rich dad; second, have him send his servant back to his people and find a wife for you; third, there’s a lot of camels involved for some reason. Right, so we want to listen to the text, and what it might teach about marriage, but not get overwhelmed by the particulars.
