Genesis 32:31: Power Made Perfect in Weakness

And as he passed over Penuel the sun rose upon him, and he halted upon his thigh.

Although Jacob halted upon his thigh, he had "power with God" to pass over the brook to meet not only Esau, but Esau with his four hundred men (Genesis 32:28, 2 Corinthians 12:9).

Genesis 32:26 - How to get your breakthrough.

And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me.

Although Jacob was weak and tied from wrestling all night, he was not going to give up until he got his blessing. As he desperately held on with all his might, crying and begging for his favor (Hosea 12:4), he got his breakthrough.

Genesis 28:22 - Jacob's vow with God.

This stone, which I have set for a pillar, shall be God's house: and of all that thou shalt give me I will surely give the tenth unto thee.

After God blesses Jacob with prosperity and a large family, Jacob remembers his vow with God and returns to this stone and builds an altar (Genesis 35:7).

Genesis 28:4 - Jacob inherits the blessing of Abraham

And give thee the blessing of Abraham, to thee, and to thy seed with thee; that thou mayest inherit the land wherein thou art a stranger, which God gave unto Abraham.

The blessing of Abraham is to make his name great by multiplying his seed into a large and great nation and by obtaining its own land possession (Genesis 12:2; 22:17).

Genesis 27:37 - Too late to change.

And Isaac answered and said unto Esau, Behold, I have made him thy lord, and all his brethren have I given to him for servants; and with corn and wine have I sustained him: and what shall I do now unto thee, my son?

Isaac initiated the blessing but it's God that fulfills the blessing (The source of all true blessings). Apparently, once the blessing is in God's hands, the blessing is irrevocable. Therefore, there was nothing Isaac could do to change what God had already ordained for Jacob (Genesis 27:28).

Genesis 27:33 - The source of all true blessings.

And Isaac trembled very exceedingly, and said, Who? where is he that hath taken venison, and brought it me, and I have eaten of all before thou camest, and have blessed him? yea, and he shall be blessed.

After blessing Jacob, Isaac states yea, and he shall be blessed because all true blessings come only from God. Isaac acknowledges the source of all true blessings in Genesis 28:3.
