In his sermon titled "Faith, Knowledge, and Works," Todd Nibert explores the profound theological implications of Abraham's willingness to sacrifice Isaac as recorded in Genesis 22 and referenced in Hebrews 11:17. Nibert argues that this narrative exemplifies the interconnectedness of faith, knowledge, and works, emphasizing that genuine faith is demonstrated through obedience and divine knowledge. He highlights that Abraham's faith was rooted in his understanding of God's unchanging nature and promises, convincing himself that God's command was right despite its horror, and that God was capable of raising Isaac from the dead. The practical significance of this sermon lies in the assurance that true saving faith produces works, serving as evidence of one's belief in God’s promises and character. This aligns with the Reformed understanding of justification, which sees faith working in conjunction with works—where true faith is validated by the actions it inspires.

Abraham's faith is illustrated in Hebrews 11:17 where he offered his son Isaac, believing God's promises.
In Hebrews 11:17, we see Abraham exemplifying true faith through a radical act of obedience—offering his son Isaac as a sacrifice. This account not only highlights Abraham's belief in God's promise of a coming Messiah through Isaac, but also his unwavering trust in God's ability to raise Isaac from the dead. Abraham's faith was deeply rooted in his knowledge of God's character, which affirmed to him that God's promises are steadfast and unbreakable. Therefore, Abraham's actions demonstrate that true faith is evidenced by works that align with God's commands, showing that our belief in God must manifest in our actions.
Hebrews 11:17, Genesis 22:1-19
God's promises are true because He is incapable of lying and always fulfills His word.
The assurance of God's promises rests upon His unchanging nature. In the sermon, it's emphasized that God cannot lie; He is perfectly faithful to His word. When He made promises to Abraham about a coming seed through Isaac, He was affirming His plan of salvation. Abraham's belief in God's faithfulness to those promises was crucial, as he acted in faith believing that even if he sacrificed Isaac, God would raise him from the dead to fulfill His covenant. This illustrates the nature of God’s promises—reliable, rooted in His character, and ultimately fulfilled through Christ. Thus, we can take comfort in the truth of God's word, knowing that what He has spoken will indeed come to pass.
Hebrews 11:19, Romans 4:20-21
Faith is essential for Christians as it directly connects belief in God with action and obedience to His commands.
Faith serves as the foundation of the believer's relationship with God, equipping them to obey His commands and fulfill His purposes. In James 2, the relationship between faith and works is illustrated—faith without works is dead. This means that genuine faith must result in actions that reflect belief in God's truth. Abraham’s willingness to sacrifice Isaac is presented as the ultimate example of faith expressing itself through works. It shows that understanding God's character leads to a faith that responds in obedience. For Christians, faith is not merely an intellectual assent; it is an active trust that leads to a life lived in accordance with God's will, demonstrating the believer's love and commitment to God.
James 2:17-24, Genesis 22:9-10
James 2 teaches that faith without works is dead and that genuine faith is demonstrated through action.
In James 2:17-24, the Apostle James argues that a faith that does not express itself through works is ineffective and lifeless. He uses the example of Abraham, who was justified by his actions when he was willing to offer Isaac. The point made in this passage is that true faith is inherently active; it compels changes in behavior and leads to obedience. This does not mean that works earn salvation, but rather that they are the evidence of a faith that is alive. James shows that faith and works are intertwined—each authenticates the other. When we see Abraham's willingness to sacrifice his son in obedience to God, it illustrates the profound connection between his belief in God’s promises and his actions—highlighting that faith manifests itself in tangible forms.
James 2:19-24, Hebrews 11:17-19
Understanding God's character is crucial because it informs our faith and assures us of His promises.
The knowledge of God's character forms the basis of a believer's faith. In the sermon, it is noted that Abraham's faith was rooted in his understanding of God—knowing that God is truthful, faithful, and powerful. This understanding gave Abraham the confidence to act upon God’s command to sacrifice Isaac, because he believed in the certainty of God's promise that the Messiah would come through Isaac. A deep knowledge of God's nature helps believers discern truth from falsehood, encourages trust in His plans, and fosters obedience, as it reassures them that God will fulfill His promises. Thus, knowing who God is empowers believers to live out their faith authentically and courageously.
