Greed and ingratitude are the negative attitudes that personified the tenant farmers. They became greedy and ingrate that they did not want to share the produce of the vineyard. Which on the first place were not actually theirs.
Are we not like them once in a while? We become too greedy that we are not satisfied with the things that we have. We want to amass wealth that we will even compromise our values. We don’t even care to share the things that we have because we have this mindset that we’ve work hard for whatever things that we have right now.
Greed and ingratitude are both mediums of the evil one.
