i completely agree God will be sure we get the correct canon.
why do you believe God allowed the wrong canon to be adopted for the first 1,500 years of the Church and He took until the 16th century to finally allow the correct canon to be known?
I do not believe God allowed the wrong canon for 1500 years, until someone else came along like Calvin to set us straight. Nor do I believe Joseph Smith either with his book of mormon.
More importantly, if you are looking for the truth, God will give it to you. (Romans 1). The problem is not that we don’t have the truth. The problem is we want the easy, self serving, make you feel better version, which of course, is a lie
