Christian Bible study - Who gives Christian apologetics authority to defend God and His Word the Bible?

The Bible clearly states that God’s ways are not our ways and so therefore no believer should have the right to read into the Bible their own desires and sensibilities!

Isaiah 55:8 "For my thoughts are not your thoughts, neither are your ways my ways," declares the LORD.

Often the devout and God fearing in their eagerness to stand in and protect God from a perceived slight on His divine character by unbelievers will sometimes read into the debate their own desires out of embarrassment.

For instance: When asked a perfectly legitimate question by an atheist like this one:

What kind of God will invent and create the largest torture chamber in the universe called hell, to incinerate for eternity, billions of fallen angels, their evil leader and billions of unbelievers?

Or 

Was God wrong to demand genocide or not when he commanded the Israelite to totally annihilate their enemies, men, woman, children and even animals?

Or 

Did God demand human sacrifice or not? Did/does God approve of slavery, polygamy or not, homosexuality, abortion, and other social issues etc?

Embarrassed and rightfully so, Christians are often quick to come to God’s rescue to find counter-verses to argue that God shares our modern sensibilities on these matters when he obviously does not. However this is understandable because no believer would want to be on the wrong side of moral issues.

But let God and the Bible speak for itself, even if it provides gleeful atheists with plenty of ammunition to send right back. God can surely defend himself.

There are sixty six books of the Protestant Bible and many more of the RC one sourced from many Middle Eastern authors who lived thousands of years ago and from different primitive cultures and with different ideas of God to our modern western ideas.

We cannot presuppose God, because after all His is God. He is sovereign and in charge. He has not fallen off His throne and made someone else in charge. We need to remember who “is the boss” so to speak and never forget that God is in charge and that we are not empowered to judge him - whether the problem is ambiguity or contradictions in the Bible or evil in the world, especially when we can’t even understand the situation enough to convict him.

Bottom line – if we believe that we are His Creation and His children, who are we to say anything to the potter or our Father when we are the clay.

“But now, O Lord, You are our Father; we are the clay, and You our potter; and all we are the work of Your hand.” (Isaiah 64:8)
