Love yourself! How to understand this sentence?

This sentence is easy to understand, that is, people who love others like themselves, who will not love themselves! We will also love others, but many times we love others for ourselves, which is purposeful love and needs love in return. Although we often say that we should love our neighbors as ourselves, it is not easy to combine faith with life. Only the love of the Lord Jesus Christ is holy love, love others without my love, and love others without my love, which has fulfilled the law. All love consists in loving others as yourself. When you can love others as yourself, you are complete. I hope all my brothers and sisters will learn to love others as themselves, just like the Lord Jesus.
