24 … for these women are two covenants: one proceeding from Mount Sinai bearing children who are to be slaves; she is Hagar. 25 Now this Hagar is Mount Sinai in Arabia and corresponds to the present Jerusalem, for she is in slavery with her children. 26 But the Jerusalem above is free; she is our mother. 27 For it is written, “Rejoice, barren woman who does not bear; break forth and shout, you who are not in labor; for more numerous are the children of the desolate than of the one who has a husband.” 28 And you brethren, like Isaac, are children of promise (Galatians 4).
“Children of promise,” that is, those born in freedom, enjoy the promise and hope of freedom, while “children of the desolate,” that is, those born from slaves, are doomed to become slaves themselves. Those born again into the Kingdom by faith enjoy the promise and hope which faith brings, while those born into enslavement to the Law are always waiting for their hope to be fulfilled.
Those who seek salvation by works will always wonder if they have done enough, while those who know salvation by faith remain confident in the promise that Christ has already done all there is to do on their behalf.
Lord, thank You for making us children of promise! Help us This Day to live freely in the blessed hope of this promise. Amen.
