Kindness and goodness is something that needs to be internalized, not just professed.
We all need strong people to stand by us and help us through life. These people are shining examples of strength and can expose those who profess to be leaders and examples to follow while in fact they are cruel to those who they feel are beneath them or cannot help them in any way.
It does no good to say we wish someone peace and happiness and then secretly treat them in a cruel manner. That is hypocritical. If we wish to do as Jesus asks, we must be strong, and treat others with kindness and gentleness, the way we wish to be treated. When we encounter the opposite, we need to remove ourselves from those people.
May we all strive to be strong, kind people.
