Well teh three you mentioned are not private interpretations. But if a person says don't drink any alcohol at all, that is what is the private interpretation.
I would not consider them insane. But if they preach it as a command from God for all- then they are bearing false witness.
The law of Christ is riiculed by so so many. Smite on one cheek, offer the next? People call that crazy for the most part!
If He were the god of common sense- the world would be a much better place to live!
But as it says in proverbs:
roverbs 14:12
There is a way which seemeth right unto a man, but the end thereof are the ways of death.
Man is fallen and common sense has fallen with us!
But if a person says don't drink any alcohol at all, that is what is the private interpretation.
So, we disagree. When someone chooses to believe something for themselves, that is the private interpretation and application of scripture. When they preach it for doctrine of god, that is false teaching of a private interpretation. In any case, we agree to keep our own rules to ourselves for our own good, and not them preach them at others to obey also.
If He were the god of common sense- the world would be a much better place to live!
There is no god of common sense. The devil has never done anything good, productive, and wise.
Man is fallen. Not common sense. Fallen man is often guilty of having no common sense, especially them that preach things that make absolutely no sense at all.
By common sense, I refer to that ability to make sense of what is obvious, and apply it properly for good success, including that of Scripture:
So they read in the book in the law of God distinctly, and gave the sense, and caused them to understand the reading.
Some call it natural good sense: the God of nature is the God of naturally good common sense, that all men, sinners and saints alike, may partake of:
Wisdom crieth without; she uttereth her voice in the streets: She crieth in the chief place of concourse, in the openings of the gates: in the city she uttereth her words.
When the believers display a lack of such common sense wisdom, that all men are lightened by Christ with, when they come into the world as sinners (John 1:9), that is when Jesus said the children of this world showed more sense than the children of the kingdom of God:
And the lord commended the unjust steward, because he had done wisely: for the children of this world are in their generation wiser than the children of light.
It doesn't save anyone's soul by displaying common sense wisdom, but it is available for all to hear and apply for themselves, and it is from God in heaven.
Afterall, God still so loves the word, that He offers His wisdom to all, even if they reject the wisdom of Scripture to be saved.
