Romans 11:19-22, in this passage, Paul warns Gentile believers against arrogance and presumption, reminding them that they were grafted into the covenant community by God's mercy, not by their merit. He stresses that the Jews were cut off because of their unbelief, and likewise, Gentiles must continue in faith or face the same judgment. The message highlights God's kindness in extending salvation but also His severity toward unbelief, urging humility and faithfulness in response to His grace.
