Romans 11:19-21

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.
