Progressive knowledge

As you know, when we learn anything, we make mistakes.  When you started using a computer you probably had the horrible experience of losing something you had taken ages to type!  You may have had the wrong idea that a computer is better than the human brain, until you found it giving you some very unhelpful commands.  Gradually you got to understand the computer better and learnt how to save documents properly and create back-up discs as an extra precaution.  So you went on learning a step at a time.

In the same way, ever since the Fall when the human race first rebelled against God, people have had wrong ideas about him and it was only by a step at a time that they got their ideas right.
