‘But what is Scripture saying? ‘Be throwing out the slave girl and her son, because the son of the slave girl will absolutely not inherit in company with the son of the free woman’. 31 Therefore on this basis brothers, we are absolutely not children of the slave girl, but on the contrary, of the free woman, the free’, (Galatians 4 v 30, 31, 5 v 1a).
Paul refers to the language of Sarah to Abraham when she requested him to throw out Hagar and Ishmael, (Genesis 21 v 10). Her words received endorsement, ‘And rulers and judges said to Abraham, ‘Don’t let it be displeasing in your sight because of the boy or your concubine. All, whatever Sarah has said to you, listen and pay attention to her voice, because your seed will be called out within Isaac’, (Genesis 21 v 12). Thus, as the Galatians could read for themselves in the Scriptures, delegated rulers and judges said that Hagar and Ishmael were indeed to be sent away from Abraham’s family. The son of the slave girl was not to share the inheritance with Isaac. In the same way, on this account, all Jews who continue to exist under 'Jerusalem' and the legal Covenant of Sinai, enslaved to seeking to obtain judicial approval by observing its written codes of law, are excluded from the ‘family’ of those brought forth as a result of the announced promise. They are excluded from the divine inheritance. Thus Jesus says to Jews, ‘Struggle to go in by means of the narrow door. For I am saying to you, many will seek after entering in and will not be able, 25 away from which the master of the house having roused up and shut the door. And you begin to stand outside, knocking the door, saying, ‘Lord, open to us’. Answering, he will say to you, ‘I don’t know you, from what place you are’. 26 Then you will begin to say, ‘We ate and drank in front of you, and you taught in our streets’. 27 And he will say, ‘I am telling you, I don’t know where you are from, stand away from me all workers of injustice. 28 There will be the lamentation and the grinding of teeth when you see Abraham and Isaac and Jacob and all the prophets within the Kingdom of God, but you being thrown out. 29 They will come from the east and west, and from north and south, and will recline in the Kingdom of God. 30 And look! Those existing last who will be first, and those existing first who will be last’, (Luke 13 v 24 – 30).
Paul comes to a conclusion. ‘Therefore on this basis brothers…’. They are his brothers on account of being fellow Jews, but more especially they are his brothers because along with Paul, they ‘are absolutely not children of the slave girl, but on the contrary, of the free woman, the free’. Paul applies the allegory and brings it to its conclusion. Paul said earlier ‘Now if you [are] of the anointed, then you are existing Abraham’s seed, heirs down from announced promise’, (Galatians 3 v 29). And again, So therefore, you are no longer existing a slave, but if a son by means of God, also an heir, allotted a share, (Galatians 4 v 7). His logic then is this, if we are heirs, ‘we are not children of the slave girl’, whose son, according to Scripture, was ‘not to be heir’ (verse 30). But we are of the free woman whose son was, according to Scripture, to be heir. We Hebrew Christians are not ‘thrown out’ like Ishmael, but accepted as sons and heirs in God’s household on the basis of God’s announced promise.
