“When Abram was ninety-nine years old, the LORD appeared to him
and said, ‘I am God Almighty; walk before me faithfully and be
blameless. Then I will make my covenant between me and you and will
greatly increase your numbers.’”
(Genesis 17:1–2; New International Version)
Genesis 17 presents a pivotal moment in redemptive history: God dramatically reaffirms His covenant promises. The Hebrew phrase “God Almighty” (El Shaddai) appearing here is profoundly significant. While its exact etymology is uncertain, many biblical scholars suggest this title emphasizes God’s strength, sufficiency, and abundant provision. By using this name, God assures Abram that His promises depend upon divine power alone, reminding him to trust God’s ability rather than human resources. Earlier readers of Scripture would immediately see the significance—after all, Abram was now ninety-nine years old; by normal human standards, his prospects of fatherhood appeared impossible. Yet it is precisely in the realm of impossibility that El Shaddai shows forth divine power.
Covenants played a central role throughout the ancient Near East. Archaeological records from cultures such as the Hittites, Egyptians, and Assyrians reveal similar treaty structures that contained mutual obligations and promises. However, Genesis 17 highlights something especially profound: God Himself initiates and sustains this covenant. Its fulfillment does not depend solely on human conduct, though obedience is called for as Abram’s grateful response.
Historically, Augustine and Calvin both underscored this truth vividly: God’s covenant promises rest ultimately upon God alone—His commitment does not waver or fade, even when human obedience falters. Paul later emphasizes Genesis 17 strongly, emphasizing God’s promise through Abraham as foundational to faith and grace (Romans 4:19-22).

“No longer will you be called Abram; your name will be Abraham,
for I have made you a father of many nations… As for Sarai your wife…
her name will be Sarah.”
(Genesis 17:5, 15; New International Version)
There is great symbolism in God’s choice to rename Abram as Abraham and Sarai as Sarah. In Hebrew culture, as in many ancient cultures, names deeply reflect identity, purpose, destiny, and even relationship to God. “Abram” means “exalted father,” while “Abraham” explicitly means “father of many nations.” “Sarai,” meaning something like “my princess,” becomes “Sarah”—“princess” with a broader, universal significance.
How striking that God renames this as-yet-childless elderly couple, reiterating and expanding His promise to them! Certainly, to surrounding cultures (and possibly even to Abraham himself), these promises must have seemed laughable. Yet, God often asks people to adopt new identities by faith, long before they see tangible evidence of fulfillment.
This renaming process speaks powerfully to believers today, affirming that God’s promises change fundamentally who we are—not simply externally, but inwardly. Our new identities as children of God, heirs of promise, and followers of Christ rest not on visible circumstances, but upon God’s faithful word. Abraham became a powerful historical example illustrating Paul’s declaration that believers are spiritual descendants of Abraham, heirs according to promise (Galatians 3:29).

“You are to undergo circumcision, and it will be the sign of the
covenant between me and you.”
(Genesis 17:11; New International Version)
Genesis 17 also introduces circumcision as the covenant’s physical sign. Modern readers may find this custom strange or uncomfortable, yet this deeply symbolic practice carried profound cultural and theological meaning for ancient Israelites. Circumcision was not unique to Israel—archaeological evidence shows some neighboring cultures practicing similar rituals—but Genesis again transforms the symbolic meaning. Now, it explicitly represents relationship with God, signifying obedience, loyalty, purity, and a distinct identity among surrounding peoples.
It must be noted that circumcision alone never ensured covenant blessing; the deeper demand was always for hearts obedient and faithful toward God. As early as Moses in Deuteronomy, unfolded clearly again in the prophets, and explicitly taught by Paul, circumcision was intended to highlight inward obedience, sincerity, holiness, and relationship. Paul emphasized strongly that ultimately, true circumcision is spiritual—a heart obedient, consecrated, and transformed by God’s grace (Romans 2:28–29; Colossians 2:11).
Circumcision thus symbolizes God’s desire for distinguishing marks within believers spiritually today: lives humbly submitted, marked by obedience, and genuinely reflecting covenantal commitments in daily lives.
Suggested Cross-References: Deuteronomy 10:16; Romans 2:28–29; Colossians 2:11–12.
In Genesis 17’s historical context, the covenant-making structure closely parallels ancient Near Eastern treaties. Kings frequently stipulated covenants with subordinates, outlining expectations and mutual responsibilities. God’s promise to Abraham follows similar recognizable structures culturally, yet importantly elevated and personal—highlighting especially the unshakeable nature of divine faithfulness above human treaties subject to shifting conditions.
Additionally, archaeological findings from the ancient city of Nuzi in northern Mesopotamia offer particular insights into surrogate practices (explored previously in Genesis 16), while circumcision’s widespread practice and cultural meaning are documented across various cultures within this region.
Genesis 17 beautifully utilizes repetition intentionally (“I will make…,” “I will bless…,” “I will give…”), emphasizing God’s eager initiative. The narrative clearly presents God Himself as primary Actor—highlighting again divine responsibility, initiative, power, and decree in covenant-relationship establishment.
The Hebrew verb “walk” (הלכ halak) occurring in “walk before Me faithfully” is especially illuminating—expressing relationship-based obedience rather than bare legal compliance. Genuine obedience arises relationally responding personally to God’s call.
Consider singing prayerfully “Standing on the Promises” (by Russell Carter). Its lyrics beautifully remind believers of faithful promises—encouraging trust, stability, and firm identity through God’s covenantal faithfulness.
Reflecting seriously upon Genesis 17 invites deep, prayerful examination: Do we honestly rest our hopes confidently upon God’s unchanging covenant promises expressed perfectly now through Christ? Like Abraham and Sarah, are our identities shaped fundamentally by what He graciously promises us through faith—even amidst remaining uncertainties or impossibilities?
May we faithfully embrace obediently whatever spiritual markers God provides—hearts circumcised deeply from selfish desire, transformed distinctly toward covenantal fidelity.
Lord God Almighty (El Shaddai), Your promises are faithful, certain, dependable, and eternal. Forgive every momentary doubt gently but firmly reminding us: what You promise, Your divine power perfectly accomplishes.
Transform completely who we fundamentally become—identities firmly rooted not in human achievements, but in Your gracious calling and promises.
Circumcise our hearts; purify lovingly from impurities. Mark our lives convincingly by grateful, courageous, sincere obedience trusting every promise fulfilled dramatically through Jesus, descendant of Abraham, Savior of nations.
To You belongs all glory, honor, and praise eternally through
Christ—we gratefully walk faithfully with You, our Covenant-Keeper
forever sure.
Amen.
