Among other reasons. I believe the Bible as the word of God because there are verses that are scientifically accurate such as the earth being round and not resting on something which most people thought differently then.

Then there's fulfilled prophecy and many other things. I also believe based on what I've read in the Bible that my faith/religion, teaches what the Bible teaches.

I do respect the right of others to choose something else.

I believe in the Biblical description of faith which is based on evidence. I believe that there is much evidence more than what I've said here.
