Romans 11:16-22

If the first portion [of dough offered as the first fruits] is holy, so is the whole batch; and if the root (Abraham, the patriarchs) is holy, so are the branches (the Israelites). [Num 15:19-21] But if some of the branches were broken off, and you [Gentiles], being like a wild olive shoot, were grafted in among them to share with them the rich root of the olive tree, do not boast over the [broken] branches and exalt yourself at their expense. If you do boast and feel superior, remember that it is not you who supports the root, but the root that supports you. You will say then, “Branches were broken off so that I might be grafted in.” That is true. They were broken off because of their unbelief, but you stand by your faith [as believers understanding the truth of Christ’s deity]. Do not be conceited, but [rather stand in great awe of God and] fear [Him]; for if God did not spare the natural branches [because of unbelief], He will not spare you either. Then appreciate the gracious kindness and the severity of God: to those who fell [into spiritual ruin], severity, but to you, God’s gracious kindness—if you continue in His kindness [by faith and obedience to Him]; otherwise you too will be cut off.
