It is God Himself and His character who is the moral absolute of the universe.  This is why we have our internal awareness of objective right and wrong.  This is why we know good from evil.   

The Bible says that ‘all’ men…’all’…are morally guilty before God.  It says that this is the result of the real space-time Fall that occurred with the first man and first woman.  The Fall resulted in ‘all’ men standing morally guilty before God.  We are separated from a personal knowledge of and relationship with God.   

The good news is that God provided a solution to take-away our guilt status ‘in order’ to re-establish the God-man relationship.  We are truly morally guilty and we need a solution for it.  We can’t absolve our own guilt through the simple act of good deeds or good works.  Absolution requires something greater, much greater.   And this is where the substitutionary, propitiatory death of Christ is needed and fits in.  We need a solution for our true moral guilt before the absolutely good God who is there.  That is our need.  Christ’s substitutionary death is the solution.
