Do you approach the Bible with your mind? If so, you have made your first, and the most grievous, error.
I wondered for almost twenty years about life, God, Jesus; I sought out other religions and spiritual paths, I looked and looked. Eventually, one day, I went to an Orthodox Liturgy, and was introduced to the priest there. As I was explaining my journey, the priest answered me in a way that was the truest words ever spoken on understanding the Bible. Using both words and gestures, he answered:
"First learn what's in here (pointing to the heart);
THEN learn what's in here (gesturing his hands as if opening a book, representing the Bible)".
That is when the Bible became more clear to me.
Put the Bible aside for awhile. Discover your own heart. If it is open enough, your mind will follow. If it is not, you can never understand.
