21 Tell me, ye that desire to be under the law, do ye not hear the law? 22 For it is written, that Abraham had two sons, one by the handmaid, and one by the freewomen.23 Howbeit the son by the handmaid is born after the flesh; but the son by the freewoman is born through promise.24 Which things contain an allegory: for these women are two covenants; one from mount Sinai, bearing children unto bondage, which is Hagar.25 Now this Hagar is mount Sinai in Arabia, and answereth to the Jerusalem that now is: for she is in bondage with her children.26 But the Jerusalem that is above is free, which is our mother.27 For it is written,
Rejoice, thou barren that bearest not;
28 Now we, brethren, as Isaac was, are children of promise.29 But as then he that was born after the flesh persecuted him that was born after the Spirit, so also it is now.30 Howbeit what saith the scripture? Cast out the handmaid and her son; for the son of the handmaid shall not inherit with the son of the freewoman.31 Wherefore, brethren, we are not children of a handmaid, but of the freewoman.
THE CHILDREN OF PROMISE.
This lesson is amply expounded in my commentary on the Epistle to the Galatians. It is unnecessary to repeat the exposition here, for it may be found and read there. He who desires further information on the subject may read the postils on the epistle lesson for the Sunday after Christmas and that for New Year's Day. There he will find all information. Thus will be obviated the necessity of repeating the discourse in various places.
