The very day I got born again in 1994 at the age of 31 I knew that I knew that I knew that the Bible was the word of God and I had never read the Bible before that I didn't even have one and not too long after that the Lord revealed to me once again that the Holy Bible is his word and this happened a few more times in the first few years I was born again and I never looked back ever since even though I got heavily into the Greek and Hebrew were different manuscripts and different translations and versions and reading a lot of good books but the bottom line is I knew that I knew that I knew that what we call the Holy Bible was God's word, thank you Jesus
