Romans 3:19-20
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].
Romans 5:1
So, since we are made right with God by [our] faith, we have peace with Him through our Lord Jesus Christ.
1 Corinthians 6:11
And some of you have practiced such things, but you were washed [i.e., from your sins. See Acts 22:16]; you were dedicated [i.e., set apart for God's service]; you were made right with God in the name [i.e., by the authority] of the Lord Jesus Christ, and by the Holy Spirit of our God.
Ephesians 2:3
All of us [Jews] also once lived among such people, fulfilling the improper cravings of our physical being and doing what our bodies and minds desired. In this natural [unconverted] state we were deserving of [God's] wrath, just like the rest [of mankind].
1 John 1:9
[But] if we confess our sins [to God], He is faithful [to His promise] and righteous [in His judgment], and will forgive us of those sins and cleanse us from all of our wrongdoing.
Revelation 1:5
[It is also] from Jesus Christ, who is the Faithful Witness [to the truth], the Firstborn from the dead [i.e., the first One raised never to die again], the Ruler of the kings of the world. May there be honor and power forever and ever to Christ, who loved us and released us from our sins by His blood [Note: Some manuscripts say "washed us" since the two words are spelled almost alike].
