As Jesus is the cornerstone upon which the Church is built, so are his teachings the unifying cornerstone of Christian doctrine.
Envy in the Church
"What right do they have to be leaders? They’re just new." "She can’t be in charge. She hasn’t been around long enough?" "Why did they put him in charge of things? He’s a man and we need more women in leadership." These and other petty jealousies are common to business and unfortunately also the church. Jesus discussed the idea of envy in Matthew 20:1-16 by using an example of people hired as laborers a number of times throughout a harvest day. He gave them all the same wage, no matter how long they had worked. Was it just by our standards? Of course not. That is not the point. The exaggeration is to point out that even when justified, envy is not the right reaction for those who already have the greatest blessing of all, the kingdom of heaven.
