The follower of Christ should always deal with people with genuine care motivated by the love of God. Our behaviour toward others is motivated by God's love for us and should be independent of how others treat us.
Matthew 5:43,44 You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you
The apostle Paul, writing to his "son in the faith", Timothy, said:
2 Timothy 3:10-17 But you have carefully followed my doctrine, manner of life, purpose, faith, longsuffering, love, perseverance, persecutions, afflictions, which happened to me at Antioch, at Iconium, at Lystra––what persecutions I endured. And out of them all the Lord delivered me. Yes, and all who desire to live godly in Christ Jesus will suffer persecution. But evil men and impostors will grow worse and worse, deceiving and being deceived. But you must continue in the things which you have learned and been assured of, knowing from whom you have learned them, and that from childhood you have known the Holy Scriptures, which are able to make you wise for salvation through faith which is in Christ Jesus. All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work.
I hope you have found this helpful.
