The never-circumcised Noah "found grace" in the eyes of God. He was justified or made just. Indeed, he was then also pronounced to have been rendered just — and therefore to be just, in the eyes of God. Then God brought Noah and his family to safety, inside the ark — quite before the rainstorm began. Only thereafter were they all 'baptized' — by the rainwater falling on the roof of the ark.43 So the whole family was justified, before they were baptized (by way of sprinkling from above).
We might also point out that not just Noah and his family but even all the animals with him in the ark were advantaged by God's Covenant. The mere fact that those animals could not understand what was going on, did not mean that they could not be preserved. Nor, after the flood, does their ongoing inability to understand the covenantal significance of the rainbow -cause them to forfeit the benefits of that Covenant. Genesis 6:18-22 and 9:8-17.
Abraham too was justified in full — long before he was circumcised.44 Even after the institution of Circumcision, no Israelitic women — Israelitic by birth or by choice — were ever circumcised.
Indeed, that was not even possible. Yet many such uncircumcisable women were justified in full — such as Sarah, Rahab, Ruth, Elisabeth, etc.45
Conversely, Esau (and probably also Ishmael) — though circumcised in childhood — was never justified.46 On the other hand, David's first-born son by Bathsheba was justified before and without Circumcision — before he then died in infancy.47 For Circumcision was only for the living — and never for the dying. Nowhere in God's Word do we detect any desire to circumcise the dying — whether they be dying infants or dying adults. At Calvary, Circumcision was replaced by Baptism.48 So those modern Sacramentalists who scurry to baptize the dying, are far removed from the scenario of Scripture.
9. The circumcised Abraham and his uncircumcisable womenfolk
Abraham had already44 been justified by God — long before both he and his entire circumcisable household were commanded to be circumcised.49 Indeed, as already seen above50 -Circumcision never justified anyone.
After the institution of Circumcision, it was very disadvantageous for covenantal males to be left uncircumcised. God Himself declares to Abraham: "I will establish My Covenant between Me and you, and your seed after you in their generations…, to be a God to you, and to your seed after you…. He who is eight days old, shall be circumcised among you…. The uncircumcised male child whose flesh of his foreskin is not circumcised, shall be cut off from his people."51
This can only mean that the male Israelite was conceived and born within the Covenant prior to his subsequent Circumcision, and that he himself was thus in Covenant with God from his very first coming into being embryonically. Judges 13:5-25; Psalm 139:13-14; Jeremiah 1:5; First Corinthians 7:14. Otherwise it would not be possible for the infant, through the neglect of his own parent, to have "broken" the Covenant — if and when he was not later circumcised on the eighth day after his birth.
Moreover, the female Israelitess — whether embryo, baby, child or adult — was always altogether uncircumcisable. Yet she too was in Covenant with Jehovah — even prior to her birth, and indeed throughout her earthly existence. Genesis 30:21; 34:7-16; First Samuel 1:11f ; Luke 1:28-55.
So it is not Circumcision — compare, similarly, Baptism — which establishes the Covenant. Yet also non-circumcision — compare, similarly, non-baptism — is certainly one of the ways a Covenant already operative pre-circumcisionally (and/or pre-baptismally), can be broken. Genesis 17:2-14.
