Leviticus 20:4 And if the people of the land do any ways hide their eyes from the man, when he giveth of his seed unto Molech, and kill him not: 5 Then I will set my face against that man, and against his family, and will cut him off, and all that go a whoring after him, to commit whoredom with Molech, from among their people.
If a man in the nation of Israel offered his child to the demon Molech and another knew and overlooked it then he was wrong. God would discipline this man.
It is so easy to think that I am just minding my own business when we will not stand against sin but there is some sin that requires us to stand up for the Lord and truth. He makes that clear. No doubt that for many years many have been too judgmental and critical of things that are not clearly taught in the Scriptures. That can cause us to overlook other things that are much more important.
God’s people must stand for truth and right!
