THE MYSTERY OF THE "SELFSAME DAY" (Continued)
The next use of the term selfsame day is found Genesis 17:23, 26.
V 23 And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham's house; and circumcised the flesh of their foreskin in the selfsame day, as God had said unto him.
V 26 In the selfsame day was Abraham circumcised, and Ishmael his son.
God made a covenant with Abraham. The names of Abram and Sarai were changed to Abraham and Sarah respectively as God explained the requirements of the covenant. A name change connotes a change of nature. After this change of "nature," God promised Abraham a child, Isaac, by Sarah who was well past childbearing age. Everything about the covenant meant invoking the supernatural Power of God through faith and obedience. Abraham was so astonished until he "fell upon his face, and laughed, and said in his heart, Shall [a child] be born unto him that is an hundred years old and shall Sarah, that is ninety years old, bear?"- Genesis 17:17. Such joy exuded from Abraham until he worshipped and laughed at the same time. God named the unborn child Isaac (he laughs) possibly as a result of the ecstatic praise Abraham gave Him at the good news. God made it clear that in Isaac He would establish His covenant for an everlasting covenant and with his seed after him. Abraham obeyed God and sealed the covenant in obedience by circumcising every male in his house the selfsame day.
Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ. – Galatians 3:16
