Jesus was unpopular in his day. He was not the superstar many of us consider him to be now. He associated with and ministered to the prostitutes, tax collectors, criminals, and the poor. The wealthier Jews found Jesus contemptible and his followers detestable. Jesus served people without regard to their status. He did not engage in favoritism. It is safe to say that Jesus was not tolerant of the excuses and justifications made by the sinners of his day for their wrongdoings. However, after the Christ's departure from this world, his name was venerated for his compassion and kindness to the sinners and to all living souls (Matthew 25:35-40).
This is a profound message. For if we are to do as Jesus instructs us, we must show compassion to all humans regardless of their beliefs, attitudes, behavior, etc. Jesus did not make his love conditional on people's willingness to conform to his expectations. If any person were to do today what Jesus did in his time, that person would be run out of town.

There are some church leaders and concerned citizens who minister to violent criminal offenders in prison. This is not a fashionable job. These selfless humanitarians are seldom acknowledged for their work in this area. Not everyone is meant to work with criminals. What I think we can all do is develop the understanding that even the most corrupt and immoral people are our brothers and sisters, including the criminals who have violated our most sacred rules. I would even risk saying that we should love those people who hate us for our beliefs and who tell we are wrong for thinking them. This is idea difficult to accept, but it is worthy of consideration.

The good Samaritan proverb should answer your question .

Love everyone unconditionally. You don't need a book to know that.
