Addressing the concern over the unbelief of ethnic Israel, this message demonstrates that God's word has not failed, because His covenant promises were never intended for Abraham's natural descendants collectively, but for a true spiritual remnant. Drawing from Romans 9:6–9, the sermon contrasts Ishmael and Isaac to show that physical lineage alone does not secure salvation. Instead, true children of God are formed through sovereign, supernatural grace—brought from death to life by the power of God just as Isaac was born by divine promise.
