“And to the angel of the church in Sardis write, ‘These things says He who has the seven Spirits of God and the seven stars: ‘I know your works, that you have a name that you are alive, but you are dead.’” Revelation 3:1.
“And to the angel of the church in Thyatira write, ‘These things says the Son of God, who has eyes like a flame of fire, and His feet like fine brass: ‘I know your works, love, service, faith, and your patience; and as for your works, the last are more than the first.’” Revelation 2:18-19.
“Jude, a servant of Jesus Christ, and brother of James, to those who are called, sanctified by God the Father, and preserved in Jesus Christ: Mercy, peace, and love be multiplied to you. Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints. For certain men have crept in unnoticed, who long ago were marked out for this condemnation, ungodly men, who turn the grace of our God into licentiousness and deny the only Lord God and our Lord Jesus Christ.” Jude 1-4.
“But I want to remind you, though you once knew this, that the Lord, having saved the people out of the land of Egypt, afterward destroyed those who did not believe. And the angels [fallen angels, the, “sons of God” who may have had sex with women in Genesis 6: 1-4] who did not keep their proper domain, but left their own habitation, He has reserved in everlasting chains under darkness for the judgment of the great day; as Sodom and Gomorrah, and the cities around them in a similar manner to these, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.” Jude 5-7.
“In this the love of God was manifested toward us, that God has sent His only begotten Son into the world, that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.” 1 John 4:9-10.
