Among all of Jesus’s teachings, this might be the hardest: love your enemy. As far as I understand, it means neither to pardon all wrong doings of an evil person nor to force ourselves to have friendly feelings toward those who are actively hurting us. But like all of Jesus’s teachings, this concept has layers of meaning that are as relevant to people now as they were during his time.
Jesus makes the point very clear that the qualities acceptable to heaven are different from what the material world values. In John, he answers Nicodemus by saying, “Very truly, I tell you, no one can enter the kingdom of God without being born of water and Spirit. What is born of the flesh is flesh, and what is born of the Spirit is spirit.” (3:5-6)
