Bible believing and bible thumping are different things.

Christ says preach the gospel to every living creature and we read our conversations should always lead to the laws of God.
However it does say not to go door to door, and yet thats what some we know do. They pick and choose the wrong things.

That which is literal like .ie commandments, statutues, ordinances, how to treat people, how to be a good person they interpret as metaphorical. Which is a lie.

And that which is prophetical or metaphorical they take literal.

Its why Christ says in the end many will fall away because of this type of bad judgement and behavior.
