1. Accept the divine, absolute, and literal truth of the Bible.
This is by far the most important step: If the Bible isn’t the literal and absolute truth, we might as well just give up the whole game right now.
2. Redefine «literal» when needed.
Yes, the Bible is a the literal word of God. We all know that from step one. But does this mean that every word is supposed to be taken literally? The answer is yes, except in those cases where it isn’t.
For example, the Bible clearly says that God hates homosexuality. That part is literal. The bible also says that God hates mixing different fibers in clothing. That part is not literal.
…the preferred situation by far is to have everything be literally true. In cases where this is unfortunately not possible, your job as an apologist is to properly interpret the nearly literal statements to make them figuratively literal and relevant again.
