When God created us, He didn’t build robots.  Instead, He gave us a free will to make decisions and act on them…whether wise or foolish.  But it’s also our free will that gets us into trouble most times.  We bristle at being told what to do, and obeying the rules, in our mind, is optional.  Yes, our free will can become problematic!  So in this passage, the Lord is quite concise and deliberate in His laying out of our options.  We are given the choice…the decision is ours.  Will we obey and receive a blessing, or will we rebel and experience a curse?
