45 that ye may be sons of your Father who is in heaven: for he maketh his sun to rise on the evil and the good, and sendeth rain on the just and the unjust.
That’s part of the miracle of this whole thing – that the Just and the Unjust are treated the same. Job found that out. Solomon found that out. Jesus is explaining it here. He says, you don’t get rewarded here on earth for the good things that you do, or the way that you live within the confines of the law. Instead, look for your reward in the Kingdom of Heaven to come.
