Here’s the part of God’s word on our subject that I want us to focus on today: Hebrews 13:4 continues, “for God will judge the sexually immoral and adulterous.” If our secular culture is aware of this fact, most seem not to care.
Peter warned about “those who indulge in the lust of defiling passion and despise authority” (2 Peter 2:10). In this context, the “authority” is that of the Lord himself. Such people “have eyes full of adultery, insatiable for sin” (v. 14) and face severe judgment to come (v. 17).
Like Titus, you and I are called to “declare [biblical truth]; exhort and rebuke with all authority” (Titus 2:15a). All three verbs are present tense imperatives, ongoing commands from the Lord of the universe to us. To “declare” is to speak; to “exhort” is to encourage or implore people to obey what they hear; to “rebuke” is to correct and call to repentance those who do not. We are to do this “with all authority,” regardless of the response.
