The scientific method isn’t the only method. It cannot explain why the United Kingdom formed or why WWII happened.
I think it is a matter of perspective. Phil walked into a room and the kettle was boiling. Gregory was already in that room. Phil asked Gregory why the kettle was boiling. Gregory started talking about the heating element, electricity, how it heats the water, why water boils, etc. Then Bill walks in, and Phil asks Bill why the kettle is boiling. Bill responds with “because I wanted a cup of tea!”
Then, there is the historical method.
You say that there wouldn’t be a question over what sect is correct. But history records a man who lived around two thousand years ago who said he is “the only way”. He also claimed that he was God. Was he just a madman? Anyone can claim to be god. Well, no, because he had miracles to back him up. He was born of a virgin as well and ended up being executed, then somehow coming back to life, and was seen by many people. Then he was seen ascending into heaven. Not only does our past history point to this man, but his past history pointed to this man. There are writings predicting him that even outdate him. And it’s not like throwing spaghetti towards the wall, as those writings were being actively held to those people that held them - yet many of them who witnessed his miracles did not believe, one even betrayed him. And then after death, he sent his spirit to aid many people in telling the world about him. To this day, people count the year based on days since his birth.
What I tell you is good news. This man is not just a man. He is Jesus Christ. History points to him.
Salvation is a free gift from Jesus. Even the tiny amount of faith saves from Hell. And if you think this is still mean, that doesn’t disprove the reality. The fact your body will decay in the earth and you’ll probably be forgotten is a cruel fact which many don’t like, but it is reality.
Salvation is free. And it’s offered to everybody. No matter their race, age, gender or background.
