As Jesus is the cornerstone upon which the Church is built, so are his teachings the unifying cornerstone of Christian doctrine.
Poverty and Famine
Entitlement mentality affects rich and poor. Some believe that their hard work or talent entitles them to gross excesses of wealth. Others believe that they are entitled to things without working for them. Peter also misunderstood what a Messiah was entitled to (Matthew 16:21-28). His entitlement mentality temporarily put him on the side of Satan rather than God. Jesus came from privilege, became poor to save the world and now lives again in the wealthiest corner of the universe, heaven. But rich or poor, he did not consider that either entitled him not to sacrifice his life for humanity. What good is it to feel like we are entitled to the gain whole world but in so doing lose our own soul? A mentality that involves willingness to sacrifice the self for the sake of others is from God.
