Looking for a Quote from St. Josemaria Escriva on the Blessings of Marriage

St. Josemaria Escriva, the founder of *Opus Dei*, once said "God in his providence has two ways of blessing marriages: one by giving them children; and the other, sometimes, because he loves them so much, by not giving them children. I don’t know which is the better blessing." One [web article](https://surprisedbymarriage.com/2020/09/08/to-the-small-catholic-families-god-loves-you-too/) quotes this. I also read somewhere that Scott Hahn was quoting St. Josemaria Escriva saying this in his book on his journey with *Opus Dei*, which I put on hold at my local library, but don't have in my hands yet. I am trying to track down the origin of this quote. Was it something the Saint wrote and published? Was it part of a speech or homily? Was it something he just said off the cuff that someone happened to write down? If no one here knows, I will answer the question once I get Hahn's book in my hands and can track the source down.
