Good morning! People often do not treat you the way you want to be treated. You have to determine to not let that change you or how you treat others. Teach others how to treat you and others by being and example of godliness and grace.
If you only love those who are easy to love and who love you, what does that prove? Anyone can do that, but someone filled with the love of Jesus can love those who seek to misuse you, hurt you and even hate you. Jesus did that for us; just look to the cross and see.
Of all the laws and prophetic books, Jesus said it can be summed up in two things: Love God with all you are and to love others how you love yourself. Be the goodness and kindness you want to see in the world. Teach people the love of Christ by loving like Christ. Do this and you will make a great day!
