Here is another passage to ponder:
Galatians 4:21-31 (KJV)
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, the one by a bondmaid, the other by a freewoman.
23 But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.
24 Which things are an allegory: for these are the two covenants; the one from the mount Sinai, which gendereth to bondage, which is Agar.
25 For this Agar is mount Sinai in Arabia, and answereth to Jerusalem which now is, and is in bondage with her children.
26 But Jerusalem which is above is free, which is the mother of us all.
27 For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.
28 Now we, brethren, as Isaac was, are the children of promise.
29 But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now.
30 Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman.
31 So then, brethren, we are not children of the bondwoman, but of the free.
Galatians 4:21-31 (ESV)
21 Tell me, you who desire to be under the law, do you not listen to the law?
22 For it is written that Abraham had two sons, one by a slave woman and one by a free woman.
23 But the son of the slave was born according to the flesh, while the son of the free woman was born through promise.
24 Now this may be interpreted allegorically: these women are two covenants. One is from Mount Sinai, bearing children for slavery; she is Hagar.
25 Now Hagar is Mount Sinai in Arabia; she corresponds to the present Jerusalem, for she is in slavery with her children.
26 But the Jerusalem above is free, and she is our mother.
27 For it is written, “Rejoice, O barren one who does not bear; break forth and cry aloud, you who are not in labor! For the children of the desolate one will be more than those of the one who has a husband.”
28 Now you, brothers, like Isaac, are children of promise.
29 But just as at that time he who was born according to the flesh persecuted him who was born according to the Spirit, so also it is now.
30 But what does the Scripture say? “Cast out the slave woman and her son, for the son of the slave woman shall not inherit with the son of the free woman.”
31 So, brothers, we are not children of the slave but of the free woman.
Notice Hagar represents the Law from Mount Sinai. The Law that was given 430 years after Abraham (Galatians 3:17), yet it is represented by Hagar.
However believers are represented by Isaac born by the Jerusalem from above.
Do you want to be children bound for slavery (according to the flesh) or children of the promise?
Which covenant do you seek?
