I like reading the New Testament in the original Greek, but even then there are still questions. For example, my Greek text is full of notes showing variant readings and commenting on the reliability of the main text.
Without the spirit it simply is not possible to learn the truth by reading alone. Read what?
In addition to my Greek text I have about 20 different English translations and other translations in Latin, Italian, French and German.
Which of these is true? All of them or none of them? And how would I know without the Spirit?
The idea that I can simply " believe the truth by reading, choosing to believe and hoping that what I just read is the truth" makes no sense without the Spirit.
