Regarding Abraham "lying" if you read carefully he did not lie. He in wisdom gave the relevant information as his wife was also his "sister" in the sense that they were related.
I would rather look to scripture:

• Christ has been made unto me Wisdom
• If ask one lacks wisdom let him ask...

There is no good reason to lie. The Wisdom of Christ is available to all. Here is a story of a Christian girl who did not denounce her faith.

Your question reminds me of a story I heard years ago. In a repressive state where being a Christin was a death sentence. The Christians met underground and disguised bibles or memorized the entire bible to be safe, as being found with a bible was a death sentence. One evening after a fellowship meeting some Christians were stopped by the police and asked where they were coming from. One person full of God's wisdom replied our elder brother has died, and we went to read his will today
The bible is called a testament another word for will.
Wisdom is the principal thing.
