"If a man is one who, for any reason at all, rejects the Law,and Gospel of Grace through Christ, I would rather he do his worst to me for my adherence to it. Let him who will not surrender to God Almighty do his level best to destroy my reputation, to make me appear the fool, and if time and circumstance allow, let him even seek my life. But I will not have a man who refuses to surrender to God in faith, attempt to tell me that he "disagrees, but respects my opinion", for such a man is a smiling liar. It is not respect! Not respect, but cowardice. Respect of this opinion would render this man broken. He is a man who cannot find the nerve to kill me or harm my reputation, so he claims a peaceful respect.
I would rather, above all else, to see that man saved! But if not saved, I
would prefer to see him honest for once at his death.
There would be no greater failure of mine than to "agree to disagree" while the very gate of Hell closes between a poor lost sinner and myself--a sinner too, but saved by Grace."
On minor issues of conscience we can "agree to disagree" but in matters of biblical doctrine, we must stand for the Truth and not cave. If two people disagree on doctrine, someone is wrong. This rightly assumes that Truth IS knowable, too, by the way. Often "agreeing to disagree" is merely a conversation stopper because the topic is too close to home or its getting a little heated. Most "Christians" today rather dump all talk and search for God's Truth than wade knee-deep into a discussion. Its as if there's no passion for truth at all. But certainly there's a passion for self-preservation.
I think that "agree to disagree" tries to shut down the Truth as mere opinion and ejecting the knowability of Truth.
Here's a question: Did Jesus ever use that phrase, "We'll just have to agree to disagree"? If not, then why do so many professing Christians do so on doctrinal issues?
Certainly in the chapter of the "Woes" Jesus gives to the Pharises He says:
Mat 23:13 "But woe to you, scribes and Pharisees, hypocrites! For you shut the kingdom of heaven in people's faces. For you neither enter yourselves nor allow those who would enter to go in.
Mat 23:15 Woe to you, scribes and Pharisees, hypocrites! For you travel across sea and land to make a single proselyte, and when he becomes a proselyte, you make him twice as much a child of hell as yourselves.
Mat 23:16 "Woe to you, blind guides, who say, 'If anyone swears by the temple, it is nothing, but if anyone swears by the gold of the temple, he is bound by his oath.'
Mat 23:17 You blind fools! For which is greater, the gold or the temple that has made the gold sacred?
This doesn't sound like agreeing to disagree on Jesus' part. For that matter, the Pharisees didn't seem to want to agree to disagree with Him either.
Here's more Scripture:
Joh 8:31 So Jesus said to the Jews who had believed in him, "If you abide in my word, you are truly my disciples, 32 and you will know the truth, and the truth will set you free."
Isa 45:19 I did not speak in secret, in a land of darkness; I did not say to the offspring of Jacob, 'Seek me in vain.' I the LORD speak the truth; I declare what is right.
Eph 5:17 Therefore do not be foolish, but understand what the will of the Lord is.
