Luke 10:29
But, wanting to justify himself, the teacher of the law of Moses asked Jesus, "And who is my neighbor?"
Romans 3:19
Now we [all] know that everything the law says applies to those who are under [obligation to obey] that law, [Note: Here "the law" appears to refer to the Old Testament Scriptures generally, since Psalms and Isaiah are quoted. See verses 10-18]. This is so that the mouth of every objector may be stopped [i.e., from making excuses for his sin], and thereby bring the entire world under God's judgment [i.e., both Jews and Gentiles].
1 John 1:8-10
If we claim to have no sinful practices [in our lives], we are self-deceived and are not being truthful about the matter.
Revelation 3:17-18
For you are saying, 'I am wealthy; I have made plenty of money and do not need anything.' But you do not know that you are [spiritually] wretched and miserable and poor and blind and naked.
