My friend, I am not cheating you. Did you not agree with me for the usual daily wage?Take what is yours and go. What if I wish to give this last one the same as you? Or am I not free to do as I wish with my own money? Are you envious because I am generous?’ Thus, the last will be first, and the first will be last. (Mt 20:13-16)
If you discovered that Hitler, Saddam Hussein, Judas, various child molesters, murderers, or people who treated you unfairly were in Heaven would you be upset? Would you feel offended because it’s not fair? Don’t worry if you answer “yes”, because you’re not alone. However, the point that Jesus is trying to make is that we shouldn’t be concerned about God showing mercy to others. We are all sinners and none of us deserve His mercy.
I’m sure that I would be surprised by some of the people in Heaven. My main concern is that I live my life in such a way that I’ll get to see for myself one day!
