Galatians 4:22-26

²²Abraham, remember, had two sons: one by the slave woman and one by the free woman.

²³The son of the slave woman was born by human connivance; the son of the free woman was born by God''s promise.

²⁴This illustrates the very thing we are dealing with now. The two births represent two ways of being in relationship with God. One is from Mount Sinai in Arabia.

²⁵It corresponds with what is now going on in Jerusalem--a slave life, producing slaves as offspring. This is the way of Hagar.

²⁶In contrast to that, there is an invisible Jerusalem, a free Jerusalem, and she is our mother--this is the way of Sarah.k
