There's an interesting verse about Noah in Heb. 11:7, "By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark…"

God is always warning us.  In his Word.  We should be afraid of the outcome if we disobey.   But there is a funny thing about the human race, we always do the wrong things.  It's in our nature.  A mother has to teach her children to do what is right.  Don't bite.  Don't push.  Don't kick anybody.   Don't throw rocks at people.  Etc., etc.  You don't ever have to teach a child to do wrong.  They do that naturally.

The Bible says that we come from the womb telling lies.  But God gives us a solution.  He speaks to us in his Word.   Psalms119: 11 "Your word have I hidden in my heart, that I might not sin against you."  All sin is against God.  You may involve someone else, but ultimately you break the rule that God made.  Not the rule of the world.  The world doesn't care how you turn out.

Romans 4:22-23  "…being fully persuaded that what God had promised, he was able also to perform.  And therefore it was imputed to him for righteousness."

You either believe that God knows what he is talking about and by faith follow his path for your life.  Or you believe the Bible doesn't really mean what it says.

Look around you.  Who are the people that have peace in their lives.  Even in the midst of horrible circumstances.

You don't become a better person by sitting around thinking about it.  You have to determine to do better.  Pull yourself up by your spiritual bootstraps and get on with it.
