For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness,
Here it says men suppress the truth. The truth of what? The knowledge about God.
because that which is known about God is evident within them;
This knowledge they have about God, Paul says, is evident within them. But how?
for God made it evident to them.
This is how. God Himself made this knowledge about Him evident to them. You mean God did? How?
For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen,
Through His creation, they themselves, everyone and anyone calling themselves an atheist has clearly seen His attributes, His power, His nature.
being understood through what has been made, so that they are without excuse. — Romans 1:18-20
They understand through creation. They just suppress the truth in unrighteousness. In reality they have no excuse. There are no real atheists. None have ever existed.
Why do you reject the book of Mormon? It is self-authenticating. The first passage is all about several witnesses swearing that the known con artist really did read those golden pages out of a hat with magic stones.
The Book of Mormon is exactly as "self-authenticating" as the bible. The only difference is that we know for a fact that Joseph Smith was a con artist who spent time in prison for pulling cons using the same methods described in the Book of Mormon.
Nothing in the book of Mormon declared something before it came to pass. It's just one of 1000s of man-made religious books.
The Bible hasn't declared a single damn thing that has happened after it was written. Not one thing. It's like the prophesies of Nostradamus, it is full of so many vague passages and proverbs that they can be ascribed to anything post-fact.
