"So whatever you wish that others would do to you, do also to them."

(Matthew 7.12 ESV)

"Try to do unto others as you would have them do to you, and do not be discouraged if they fail sometimes. It is much better that they should fail than you should."

Charles Dickens

There is no guarantee that others will reciprocate equally well when I treat others as I well as I treat them. Maybe they will. Maybe not. Do not be upset about it.

My goal is to do what Jesus tells me and that is to treat others well.

"For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? And if you greet only your brothers, what more are you doing than others? Do not even the Gentiles do the same? You therefore must be perfect, as your heavenly Father is perfect."

(Matthew 5.46-48 ESV)
