Should you stay dumb?

This sounds a bit crazy, but most people do not say they want to be dumb; however, their actions prove otherwise.  I can say this because I have proven with my actions over and over again that I am dumb.

What I am getting at is this:  At work if I see something that should be done, I do it plus I do my current job.  By doing this, it puts a lot of effort on myself, but I feel in the long run, it helps the company and me.  Time after time I have run into people saying: “It is not my job” or “I do not know how to do that”. If they would use some initiative, then they would be considered such a good employee.  Instead, they settle on being who they are and then they wonder why they do not have anything at the end of the day.

If anyone, then, knows the good they ought to do and doesn’t do it, it is sin for them.  James 4:17 (NIV)

When I read this passage in context to what I am saying,  I find that some people know they need to read the Bible to know God more, but they really do not want to based on their actions.  Why is this?  Do they want to be dumb in God?  Do they want to be a baby in their faith?  Or, are they just happy with being mediocre?

If you do not know what you ought to do then it would not be sin if you do it, right?  I really believe this is wrong and I should believe this is wrong based on my actions!  How are your actions?  How are you doing with you actions based on your faith?
