The great temptation of barrenness is to believe that God’s blessed favor will only come to you in the form of a child of your own.
Well, it doesn’t, though it does come in the form of a child – the child Jesus, born to die for your sins.
“Rejoice, O barren one who does not bear; Break forth and cry aloud, you who are not in labor!” (Isaiah 54:1 and Galatians 4:27 [ESV])
God’s blessed favor is for you.
