What does the Bible say about love for each other?

In 1 John 2, it is reiterated that loving one another is not a new commandment but the same one that has been given from the beginning. This commandment is significant as it reflects the love of God and is a true expression of our relationship with Him. When we love our brothers and sisters, we are fulfilling the law of God because love is the essence of the commandments. This love is not merely a feeling; it manifests itself in our actions and behaviors towards one another, serving as a testimony to the world that we belong to Christ.
