1- Pray to God (whomever you may imagine him to be) asking for understanding
2- Study the background about the Bible (from non-religious sources) to see where it came from
3- Discard (or at least set aside) chuyrch claims and dogma.
4- READ it, looking up archaeological/historical sources about the places and peoples referred to
5- Be honestly critical- meaning not only looking for things that may be false- but also those that may be TRUE, and, finally,
6- NEVER let your faith rest on men, church or even orginization- but ONLY on your growing understanding of God...for it WILL take place if you REALLY want to know!
As one of Jesus' brothers put it-
James 1: 5- If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you.
