Romans Chapter 9 Vs. 9

 

God's Sovereign Choice

For this is the word of promise, At this time will I come, and Sara shall have a son. Rom 9:9

At this time...The 24th prophecy in Genesis (Gen. 18:10, fulfilled). Next, Gen. 18:14. This is the eighth prophecy concerning Abraham’s seed. It was fulfilled the following year in the birth of Isaac (Gen. 21:1-8).

This proves women didn’t eat with male guests in that day. When Sarah heard her name she arose and stood in the doorway of her tent and looked at God and the angels as they were talking to Abraham. See Gen. 18:10.

Gen. 17:19 “And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, [and] with his seed after him.” You see again here that the promise that God made to Abraham was to come through the child of promise (Isaac), the child of the spirit.

We can see the chain of blessings from the following verse (in Genesis).

Gen. 25:11 “And it came to pass after the death of Abraham, that God blessed his son Isaac; and Isaac dwelt by the well Lahai-roi.”

God’s assurance that the promise would come through Isaac, not Ishmael, was given to Abraham: At the appointed time I will return, and Sarah will have a son (a somewhat free quotation of Gen. 18:10 from the lxx).
