Romans 9:27
And Isaiah declares about [the nation of] Israel [Isa. 10:22-23], "[Even] if the number of Israelites were [as many] as the grains of sand in the ocean, [still only] a small minority will be saved.
Matthew 23:33

But consider this, you people who judge others for practicing the same things you [yourselves] practice; do you think you will escape God's judgment [for this]?
Romans 11:5-6
So, now also, there is a small minority which has been selected by God's unearned favor [i.e., to be saved].
Hebrews 2:3
how will we escape [punishment] if we neglect such a great salvation? [For it was] first announced [to people] by the Lord and then confirmed to us [i.e., the writer and other Christians] by those who heard Him [i.e., the original apostles].
