I too agree completely that the scriptures are 100% true, without fault, inspired words from God that I can fully trust in.
The problem comes when I don't understand a certain passage.
However, that doesn't mean that it is not true! It just means that my human sinful nature is causing me to lack in ability.
And just like Brandi said, that is where faith comes in.
I may not understand fully every part of the Bible, but I can still place my faith in it and believe it to be true.
Do I know every answer to every question that someone has about life, faith, God, etc? No. And that is why I choose to step out in faith and believe without seeing or knowing all the answers.
