He said, “I will certainly return to you around this time next year, and Sarah your wife will have a son.”
So one of the three mysterious visitors informs Abraham that he is coming back in a year, and that when he returns Sarah will have given birth to a son.
There is an interesting logical progression in how God is bringing about his promises to Abraham that I want you to notice.
FIRST PROMISE (Genesis 12:2)
God informs Abraham that he will make him into a great nation.
SECOND PROMISE (Genesis 15:4)
Abraham is promised an heir.
THIRD PROMISE (Genesis 18:10)
God assures Abraham that this son will come from the womb of his wife Sarah.
See how all three of these promises are interconnected.
Notice how they build upon each other.
A later promise doesn’t cancel out an earlier promise.
A later promise builds upon an earlier promise.
This is a solid God -principle you can take to the bank folks.
This is precisely how covenants work.
The new covenant based on Yeshua’s blood does NOT cancel out the covenants that came before.
They are all interconnected.
The New Covenant does NOT stand alone.
It is dependent on everything that came before.
I think this might be a good way to explain to a Christian that Yeshua did not do away with the law.
CONNECTING THIS TEACHING TO THE NEW TESTAMENT
“Don’t think that I have come to abolish the Torah or the Prophets. I have come not to abolish but to fulfill. Yes indeed! I tell you that until heaven and earth pass away, not so much as a yud or a stroke will pass from the Torah — not until everything that must happen has happened.”-Genesis 5:17
