"Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine."
Ellen White directly references 2 Timothy 4:2 in this passage.
"Deal faithfully with wrong-doing. Warn every soul that is in danger. Leave none to deceive themselves. Call sin by its right name. Declare what God has said in regard to lying, Sabbath-breaking, stealing, idolatry, and every other evil. “They which do such things shall not inherit the kingdom of God.” [ Galatians 5:21 .] If they persist in sin, the judgment you have declared from God's word is pronounced upon them in heaven. In choosing to sin, they disown Christ; the church must show that she does not sanction their deeds, or she herself dishonors her Lord. She must say about sin what God says about it. She must deal with it as God directs, and her action is ratified in heaven. He who despises the authority of the church, despises the authority of Christ Himself. GW 502.2"
"Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God."
Ellen White directly references Galatians 5:21 in this passage.
