God's Omniscience
The Identity and Attributes of God
May 11, 2025
Rev. Dr. Gabe Sylvia
Using the story of Abraham, Sarah, and Hagar in Genesis 21, the sermon teaches that God's omniscience—His infinite, instant, exhaustive, relational, and directional knowledge, revealed in Scripture—should inspire reverence, trust, courage, and rest in believers.
Summary
The sermon examines Genesis 21 (the story of Abraham, Sarah, and Hagar/Ishmael) to highlight God's omniscience: His infinity applied to knowledge. It explains that God's knowing is instantaneous, immeasurable, exhaustive, covenantal (relational), and directional (so He can provide); Scripture reveals this to us. Even knowing our sins and the worst we might say, God still pledges to keep and raise His saints. This attribute of God prompts awe and reverence and calls believers to follow Him with confidence, courage, and restful trust in His watchful care.
