There is an Israel of FLESH and an Israel of FAITH that God has FORORDAINED
and not all are children of Abraham because they are his offspring, but “Through Isaac shall your offspring be named.” (Romans 9:7)
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. (Galatians 4:22-26)
