Matthew 5:20 For I tell you that unless your righteousness surpasses that of the Pharisees and the teachers of the law, you will certainly not enter the kingdom of heaven.
How good do you have to be to get into Heaven?
Well, the Pharisees made an art out of doing the right thing at the right time and shamed anyone who did not live up to that goal!
Jesus reminded the disciples we have to be totally righteous to get into Heaven… But because that is physically impossible, we must rely on His forgiveness and mercy!
