Cogito, ergo sum is a Latin philosophical proposition by René Descartes usually translated into English as “I think, therefore I am“. The phrase originally appeared in French as je pense, donc je suis in his Discourse on the Method, so as to reach a wider audience than Latin would have allowed.

We’ve probably all heard this phrase by Descartes, right?
“I think, therefore I am.”
Have you heard of this one?
“I think, therefore I am right.”

This is going to be really quick and fast.
If you speak of your doctrine or theology starting with the words “I think…” or “I believe…” then you may need to study a bit.

When you describe your doctrine or theology, you should start with these words:
“Scripture says…”

Too many people inject their own thoughts, emotions, and ideas into their theological beliefs.  Sometimes doing so results in changing or denying the scriptures.
Sometimes doing so requires us to change or deny the very words of Yeshua or Yehova.
We probably shouldn’t do that.

Let your yes be yes, and let your no be no.
Start your theology discussions with “Scripture says…” and you can never go wrong.
