Hated without reason

There was a good missionary family serving in North India. God enabled them to serve the whole community. There were about 20 families in the community, and they were familiar with all of them. When children in a community have a birthday or any special occasion, they will come to him to get blessings. Thoughtfully, he will give them books of general knowledge as gifts. He also started a tuition centre for underprivileged children in his home. From the neighbouring slum, children used to come. The community did not like those poor children coming to their locality. They said that the poor will steal or create ruckus. Regardless, he continued to serve the poor. One day evening as children began coming, neighbours came and argued with the family and started beating him. Police were informed and they also came. A case was registered and serving poor kids was abruptly stopped. The family wondered how they had served the community who were ungrateful and could become violent against them. How true is the verse: “They hated me without cause.” (Psalms 69:4; John 15:25) This verse applies to Lord Jesus Christ, yet, the Lord said His followers also will be persecuted like the Master. (John 15:20)
1) Selfish: The community people were selfish. They wanted the missionary to serve them only and not others. If he serves the kids in slums, his attention to serve their kids would be distracted or reduced.
2) Envious: In their worldview, the poor were destined by God or by fate to be poor. Helping them was not necessary. The missionary was doing a non-essential task of teaching the poor slum kids. Chief Priests, Pharisees, Sadducees and Scribes were envious of Lord Jesus Christ, so only they handed him over to Pontius Pilate. (Matthew 27:18) Cain murdered Abel, because he did not want anyone better (righteous) than him.
3) Future danger: The community people thought the poor kids, if well-educated, will become competitors to their own children in the job market.
True Christ followers will be persecuted.
