"For this is what the promise declared:“About a year from now I will return and Sarah will have a son.”"
— Romans 9:9, NET Bible
“For this is the word of promise, At this time will I come, and Sara shall have a son.”
“For this is a word of promise, According to this season will I come, and Sarah shall have a son. ”
“For this is a word of promise, "At the appointed time I will come, and Sarah will have a son."”
“For this is the word of promise: According to this time will I come. And Sara shall have a son.”
“For this is the word of God's undertaking, At this time will I come, and Sarah will have a son.”
“For this is the word of promise, At this time will I come, and Sara shall have a son.”
It is not as though the word of God had failed. For not all those who are descended from Israel are truly Israel,
nor are all the children Abraham’s true descendants; rather“through Isaac will your descendants be counted.”
This means it is not the children of the flesh who are the children of God; rather, the children of promise are counted as descendants.
For this is what the promise declared:“About a year from now I will return and Sarah will have a son.”
Not only that, but when Rebekah had conceived children by one man, our ancestor Isaac–
even before they were born or had done anything good or bad(so that God’s purpose in election would stand, not by works but by his calling)–
it was said to her,“The older will serve the younger,”
