On this Sunday the scriptures, particularly the second reading and the gospel, draw out attention to the fact that we need to love one another. Jesus commands us, makes an urgent appeal to everyone of us to love one another. If we love one another, we will remain in His love. Just as He loved, He had love, and He remained in the love of his Father, so that he kept His word. Keeping the word of the Lord is to love on another.
In St. John in the second reading said, "It is not we who loved God first, but He who loved us, and gave us his Son as the sacrifice that will take away our sins." Therefore we should love God and one another. If we claim to love God and do not love one another, we would be liars, because our neighbor is the one we can see today with our own eyes. And if we fail to love our neighbor, who is closer and present to us here and now and claim to love God we will be telling a lie. So St. John, in the second reading urges every one of us to be of the same mind of Jesus Christ who loved us to the point of giving up his life for us.
