Well, if you look at the gospel account, Christ turned water to wine.... no grapes, no time, no aging and produced the best wine at that wedding. He healed lepers, deaf, dumb, crippled. One woman healed by touching his garment. He stopped a storm, walked on water, fed over 5000 people with two fish and five loaves or buns.... He predicted His own death and resurrection, had no bones broken but was beaten, flogged and died on a cross, only to show up 3 days later and appear to over 500 people.
Then, He ascended to heaven, in full view of many people and disappeared...
Believing these things is pertinent to being saved.
I have to ask how many of these accounts would be disputed today by man kind if it was not for one thing and one thing only>>>>>>>>>>>>>>>>>> you must believe them to be saved.
If salvation did not depend on these facts..........they would be explained away as allegorical, mythical and metaphorical........just like Genesis 1
You believe because you must.
You deny Genesis because you can say "my salvation doesn't depend on it..
Both are equally true and literal. One is tossed out because it's not necessary.
