Luke 6:27-33 talks about how we should love our enemies, not judge them and give without expecting something in return. These are such difficult things to do, right? - especially when it's your enemies. But Jesus calls us to a higher level of standard, he calls us to love others as much as we do ourselves, not hurt them, but bless them.
Jesus said that others would see Him in us by how we love each other. We can only achieve this if we are led by the Holy Spirit, and filled with the Spirit.
Luke 6:37-38 "....Forgive, and you will be forgiven. Give, and it will be given to you: good measure, pressed down, shaken together, and running over will be put into your bosom. For with the same measure that you use, it will be measured back to you.”
