2 Timothy 4:2
Preach the Word; be prepared in season and out of season; correct, rebuke and encourage--with great patience and careful instruction.

Revelation 3:19-22
As many as I love, I rebuke and chasten. Therefore be zealous and repent. Behold, I stand at the door and knock. If anyone hears My voice and opens the door, I will come in to him and dine with him, and he with Me. To him who overcomes I will grant to sit with Me on My throne, as I also overcame and sat down with My Father on His throne. “He who has an ear, let him hear what the Spirit says to the churches.”
