What is the most important thing in life? Money? Health? Knowledge? Creed? Love is the most important thing.
But what is love? There is a love between men and women and a love between friends. However, scripture tells us to love our neighbour.
Who is my neighbour? Everybody is my neighbour. This means that we must love our enemy as well as God. Loving God is the highest command.
How is God's love? He loves the bad and the good. It was this love that led to Hazrat Isa's sacrifice for sinners. Through this sacrifice we receive forgiveness of our sins. Thus the highest attribute of God is love.
We are commanded to love like Hazrat Isa loved us. How can we love like this? By receiving His love through the Holy Spirit.
