What's allowed for Christians, although this fallen/sinful world tries all the time to persuade us this would mean to judge.
Correct, rebuke and encourage (especially strict), to threat, to convict, to badge, to examine, to decise, to asses and to expose something.
–> on a positive way (compare Proverbs 9:8, Proverbs 27:6, Matthew 18:15, Luke 7:43, Luke 12:57, John 7:24, 1. Corinthian 2:15, 1. Corinthian 5:12, 1. Corinthian 10:15, Ephesians 5:10-11, 1. Timothy 5:20, 2. Timothy 4:2, 2. Thessalonians 3:14, Hebrews 3:13, 2. Timothy 1:13, 1. John 4:1, Revelation 2:2 and so on).
Dear brothers and sisters in Jesus Christ, do never stop to call sinful actions sinful, just because Gods enemy, the "God of this world" (Luke 4:5-7) and his followers try to persuade you this would mean "to judge", forwhy anyone who permits the enemy to "falsify"
the truth on this way can't be useful for the Lord.
