Did you know that God was El-Shaddai? Genesis 16-19

Genesis 17:1-2 (NASBStr)

 Now when Abram was ninety- nine years old, the Lord appeared to Abram and said to him,

“I am God Almighty;

Walk before Me, and be blameless.

 “I will establish My covenant between Me and you,

And I will multiply you exceedingly.”

God had revealed Himself to Abram many times.  In this occasion God refers to Himself as "El-Shaddai"  - God Almighty.   God is about to repeat the promise to Abrram that He will make him a mighty nation and and bless his descendants after him.   Abram has heard this promise before and will hear it again.   This time, the emphasis is not on the promise, but on El-Shaddai.   Over the next few chapters Abram is going to see just how "almighty" God can be.   Shaddai has a couple of difference meanings, depending on where you read about it.   One interpretation of the Hebrew word is that it means the great destroyer.   It is used in this context in other places in God's Word.  In the Greek version of the Hebrew Old Testament the word is often translated "to  overpower" or "to destroy".     However, it is also used in Genesis 49:25 to mean "breast" signifying "sufficiency" or "nourishment" (meaning from the mother's breast comes sufficient nourishment.   Perhaps, El-Shaddai means both.  Perhaps God is sufficient for us which makes Him the "Almighty" and He is the destroyer, adding to the fact that He is to be feared and awed as the sufficient One, the overpowering One, the mighty One.  The point in the above text (this is the first time this name for God is used) is that God will be sufficient to supply what Abraham needs in a son to keep His promise to Abraham.   God will not only establish the covenant (this was an unconditional covenant made by God purely out of God's grace and mercy), but will keep it because HE IS EL-SHADDAI!   There is nothing that God promises He can't supply.  He is the Great Shaddai.   We can rest assured that not only does He make promises and fulfills them, He CAN make promises He wishes to fulfill because He is the Almighty.   Nothing is bigger than God.   Nothing is more powerful than God.   In the next chapter God will destroy Sodom and Gomorrah and, yet, save Lot and his daughters. He does this because He promised Abraham and He can do it.   He killed Lot's wife because of her lust for Sodom.   God is the God Almighty - El-Shaddai: Sufficient and Powerful.
