Something to think about.
 
27 And just as each person is destined to die once and after that comes judgment, 28 so also Christ was offered once for all time as a sacrifice to take away the sins of many people. Hebrews 9:27-28
 
In the history of events past and future, this happened once. It will never happen again.  Christ was offered for all humanity, but not all of humanity will be accepted. It says "many people" not all people. This sacrifice will not apply to those who decide to stand for judgment based on their own merit. It is like going to trial with no attorney, against the most successful prosecutor of all time. And he has the truth of your crime fully exposed. You will not stand a chance. Let Christ's sacrifice be what takes away your sin so that you may be one of the many.
