Authentic kindness hinges upon our intent behind that action. If it is because you are thinking the person(s) involved will repay that kindness in some way, donate to your cause, join your team, or give you what you want your “self” is still at the root of your actions. Acts of authentic kindness come from within as you view the person through Gods eyes. It is not an easy thing, but we are called to great acts of kindness, love, forgiveness, and servanthood while expecting nothing in return. It is that simple although not easy, many times.
Dig up your shallow roots of self and replant with nourishment, care, and cultivation so that your roots grow deep in understanding of the Divine. It is then you become authentically genuine in all of your words, actions, and behaviors for Holy Spirit replaces self and you see people differently. Start digging!
