The sermon, rooted in Romans 11, affirms that God has not permanently rejected Israel, despite the widespread unbelief among the Jewish people, because His sovereign choice—based on grace, not human merit—has always preserved a remnant. Through the lens of Old Testament figures like Elijah and prophetic texts, it emphasizes that God's election is not determined by lineage but by His foreknowledge and unearned favor, which extends to both Jews and Gentiles. The current rejection of Christ by most Jews is not final but serves a divine purpose: the salvation of the Gentiles, which in turn provokes Israel to jealousy and emulation, ultimately leading to a future restoration of national Israel. The passage concludes with a profound meditation on God's incomprehensible wisdom and glory, reminding believers that all things originate from Him, flow through Him, and belong to Him, calling for humility, awe, and worship in response to His eternal, unsearchable ways.
