Galatians 4:27

‘For it is written, “Rejoice you who are barren and do not bear, Break forth and cry you who do not suffer birth pains, For the children of the desolate are more than she who has a husband.'

A quotation is now cited from Isaiah 54:1. It refers to the divine principle that those who initially ‘have not' are the ones who, through God's mercy, often eventually ‘have', because ‘their Maker is their husband' (Isaiah 54:5). They do not look to a husband of the flesh but to a husband of the Spirit. And thus the seemingly barren become fruitful. Paul then refers this to Sarah who had been barren and had produced no children. Possibly he is considering the fact that through natural relations with her husband Sarah could not bear. When it came to having children she ‘had no husband'. Thus God Himself had to intervene, almost acting as the husband in producing a child for her. But she will yet rejoice and have many children, more than she who first bore. She who was barren will produce many children. For Sarah represents the new Jerusalem which will indeed produce many children.
