Study Bible

But I will establish
The phrase "I will establish" comes from the Hebrew word "קִים" (qim), which means to confirm, make firm, or set up. This indicates a divine action of God, emphasizing His sovereign will and power to bring His promises to fruition. In the context of the Abrahamic covenant, it underscores God's initiative and faithfulness in fulfilling His promises, independent of human effort or merit. This assurance is a cornerstone of faith, reminding believers that God's plans are steadfast and reliable.

My covenant
The term "covenant" is derived from the Hebrew word "בְּרִית" (berit), signifying a solemn agreement or promise. In biblical terms, a covenant is a binding commitment, often sealed with a sign or sacrifice. Here, it refers to the specific promise God made to Abraham regarding his descendants and the land of Canaan. This covenant is central to the narrative of the Bible, as it sets the stage for the unfolding of God's redemptive plan through the lineage of Isaac, ultimately leading to the coming of Christ.

with Isaac
Isaac, whose name means "he laughs" in Hebrew, is the child of promise, born to Abraham and Sarah in their old age. His birth is a miraculous event, highlighting God's power to bring life and fulfill His promises against all odds. Isaac's role as the heir of the covenant is crucial, as it establishes the line through which God's promises to Abraham would be realized. This choice of Isaac over Ishmael underscores the theme of divine election and grace, as God's purposes are accomplished according to His will, not human expectation.

whom Sarah will bear
The mention of Sarah bearing Isaac is significant, as it reaffirms God's promise to Abraham that Sarah, despite her old age and previous barrenness, would be the mother of nations. This miraculous birth is a testament to God's ability to bring about His purposes in seemingly impossible situations. It also highlights the importance of faith and patience, as Abraham and Sarah had to wait many years for the fulfillment of this promise, teaching believers about the virtue of trusting in God's timing.

to you
The phrase "to you" personalizes the promise, emphasizing that God's covenant is not just a general or abstract concept but a specific and personal commitment to Abraham. This personal aspect of God's promises is a source of comfort and assurance for believers, as it reflects the intimate relationship God desires to have with His people. It reminds us that God's plans and purposes are intricately woven into the lives of individuals, and His promises are meant to be experienced personally.

at this time next year
This specific timeframe underscores the certainty and imminence of God's promise. By providing a concrete timeline, God reassures Abraham of the reliability of His word. This detail also serves to build anticipation and faith, as Abraham and Sarah are given a tangible point of reference for the fulfillment of God's promise. It highlights the precision of God's plans and His control over time and history, encouraging believers to trust in His perfect timing for their own lives.
