The problem with opinions is that there is no certainty. Opinions, at best, are your best guess. Therefore, there is no solid ground to stand on.
The beauty of truth is that it’s solid. Truth is the way it is, and there is no other way. Opinions leave you on sandy, shifting ground.
Opinions can be changed quite easily. Opinions are typically based on experience, so when you get more experience, or perhaps a different experience, your opinion changes.
Sometimes you are caught in a middle ground where you could go, as we say, “either way.” Kind of like cheesecake.
I could go either way on cheesecake. The last couple cheesecakes I’ve had were pretty good, but the vast number of cheesecakes I have had in my life were disgusting (I recently discovered that the best cheesecake I have ever eaten in my life is actually a tort). I could go either way. My opinion is divided on cheesecakes.
Elijah spoke to the people of Israel who were stuck in between a desire to worship God and a desire to worship Baal. They were at a point in history where things were bad, but not all that bad, just the beginning of Israel’s downfall, and when it came to worship, their experience told them they could go “either way.”
So they did. And Elijah said to them, “How long halt ye between two opinions? if the Lord be God, follow him: but if Baal, then follow him.”
Israel was the prototypical double-minded man who is unstable in all his ways. If I can go “either way” on cheesecakes, do I eat the next cheesecake I am offered? I don’t know, maybe.
There is no certainty there. We need the truth about cheesecakes, just like Israel needed the truth about what God to worship. To be a person who lives on opinions is to be tossed about to and fro with every wind of doctrine.
There is no stability, no truth, no safe harbor, no solid ground to stand on. Opinions are dangerous. Opinions should be avoided when truth can be readily had. Dig down to the solid rock of God’s Word, which requires time, effort, and patience. Resist the urge to throw up a shack on any empty spot of land. Do the work to know the truth.
“Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.” When you do the work, you won’t be ashamed; if you go with the latest opinion, be ready to look like an idiot.
