Who makes it possible for you to know Jesus's word? How do you know about the Crucifixion and Resurrection? It isn't through Tacitus or Josephus, though they mention Jesus in passing. It's through Scripture -- which was collected, reviewed, and approved by the Church, out of the hundreds of quasi-Christian "scriptures" circulating in the Mediterranean world in the century after the death of Christ.
You can't reject the Church and not reject her work on behalf of her Head. Which is the only way you know Him.
No, sorry but it's through the guidance of the Holy Spirit. You see, God helps you understand His book, if you are first and foremost His and second you ask His help.
