This may appear as a cartoon, but it contains a dead serious message. No one gets to Heaven unless they obey God and pass the test. As St. Theresa said, "Heaven is earned very hard." As pilgrims upon earth, we are migrating as it were to our future home, but no one just walks through the Pearly Gates. There is much vetting to get in, and many are turned away.
"For many, I say to you, shall seek to enter, and shall not be able." (Luke 13:24)
