God’s Covenant with Abraham-Sarah
God’s promise to a husband-wife union could be revealed through the husband or wife and will be fulfilled to them as a unit. Because the husband and wife are one, a promise to one is a promise to the two-in-one and will be fulfilled to them together. God interacts with husband and wife as one and illustrates the relationship through his covenant with Abraham-Sarah: a conditional promise to be God to all that worship and serve him.
We discuss God’s interaction with Abraham regarding his conditional promise to be God to all that worship and serve him. The promise was for Abraham-Sarah as a union, their descendants, and all humanity. However, God revealed the promise to Abraham as an individual. The context of the interaction enables an understanding of aspects directed at Abraham or Sarah individually and aspects directed at Abraham-Sarah as a union. God provides a message through the interaction: that his promise to a husband-wife union could be revealed through the husband or wife but will be fulfilled for them together as a unit.
Abraham understood the message but doubted the promise could be fulfilled for him and Sarah considering their age. He appealed for Ishmael in an apparent attempt to “help” God find a path to fulfillment of the promise [Genesis 17:17–18]: “Then Abraham fell on his face and laughed, and said in his heart, ‘Shall a child be born to a man who is one hundred years old? And shall Sarah, who is ninety years old, bear a child?’ … ‘Oh, that Ishmael might live before You!’” Then God clarified the promise: “No, Sarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My covenant with him for an everlasting covenant, and with his descendants after him” [Genesis 17:19]. Thus, God explained to Abraham that the promise is for Abraham-Sarah and will be fulfilled to their descendants through a son of their flesh. He spoke to Abraham to convey a conditional promise for Abraham-Sarah.
It is perhaps easy to understand that the promise of a child to a husband or wife is a promise to the husband-wife union. However, we may need greater consciousness of the message to appreciate its other implications. Whether in regard to wisdom or knowledge, physical possession, child bearing, or any other areas of human need, God’s promise to a husband or wife belongs to the husband-wife union and will be fulfilled to them as an indivisible unit. They need to be functionally together and interact with God as one in order to receive fulfillment of the promise. They could lose the promise if one person should become greedy and seek to claim individual ownership of any part.
We discuss God’s interaction with Abraham as described in Genesis 17 to understand the message of the covenant as it relates to husband-wife interactions and relationships.
