So we each rely ultimately on our faith.
Matthew 16:
4": A wicked and adulterous generation seeketh after a sign; and there shall no sign be given unto it, but the sign of the prophet Jonas.
"21": From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day.
"An empty tomb is there to prove my Savior lives."
The Word of God cannot be disproved. Man's word has often been disproved.
Hebrews 11:
"3": Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
6": But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
No. We rely upon evidence and theories are built and tested to explain the totality of that evidence.
The Word of God cannot be disproved.
Would that this were so, but it's not.
Both these (and about a half dozen more) were written by Dr. Bart D. Ehrman, who started his journey as a born-again Christian seeking the original and true Word of God. Start with the first book above as it lays out that search in the first chapter, and is written for the layman. The other work is definitely written for the scholar, but is still worth the read.
Man's word has often been disproved.
Science is self-correcting (the scientific method) whereas religion cannot, by its very nature, be so. However, what many lay persons see as "disproved" is more often than not simply a refinement in light of new data. For instance, the age of the Earth -- geologists had already figured out the Earth to be on the order of at least millions of years old by the end of the 18th century, based on nothing more than the layers in the geological record. As dating methods became more precise that number changed and became more refined. It wasn't until someone hit upon the idea of dating (by various methods) meteorites (the leftovers from the beginning of the Solar System), that the age of the Earth was finally pegged at some 4.5 billion years. Dating of moon rocks and additional meteorites have only confirmed this age. The same general ideas have been applied to other sciences, including evolutionary biology. Each new piece of evidence is a test of a theory, and Darwin's theory has proven to be quite robust in light of new evidence discovered over the past 150 years.
