Ultimately every single believer will tell you one of the same two stories - either they believe now as they always have, and the thought of unbelief is something they can't countenance; or they were intellectually unimpressed by the arguments of faith until, one day, they just had a feeling it was true.
Not every single believer.
I will tell you I read the Bible 1 and 2/3 times (I was in the book of Romans the second time) when I came to some conclusions. I was not raised in church. My dad was not a believer, my mom was nowhere to be found.
I came to those conclusions because of what I read, not what I was told, not because I had a feeling.
I believed the Genesis account of creation 57 years ago and still do today. If you want to prove what I believe is wrong about what Genesis says, feel free to do so.
I believe the Universe declares God.
I believe the fulfilled prophesies. declares God.
I believe some facts declare God.
....Science discovered that life was in the blood some 360 year ago. That was after the KJV bible. But the Greek Septuagint had Leviticus 17:10-14 years before the time of Christ. These verses tell us that life is in the blood.
God tells me where the universe came from, where I came from and why I am here.
Science tells me "We don't know where the singularity came from, or why".
Science tells me "We don't know where life came from or why".
We just know these things happened we are here.
Therefore I choose to believe God's version rather than science.
"John 5:39 (KJS) Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me."
