"Rivers do not drink their own water; trees do not eat their own fruit; the sun does not shine on itself, and flowers do not spread their fragrance for themselves. Living for others is a rule of nature. We are all born to help each other. No matter how difficult it is, life is good when you’re happy; but much better when others are happy because of you." Pope Francis.

The Son of God could have easily remained enjoying the love of the Father and the Holy Spirit. But the very nature of God's love involved only the internal love of the Persons for each other, but "ad extra" love to human beings. The Word became flesh to show us the love of God by giving his life on the cross for our salvation. He emptied himself for our sake. As we prepare for his coming, he has stressed the need for us to follow his example. We are called not to be focused on self love, but to be more focused on love of the other. God pours out his love upon us, so that we can pour our love upon others. If we keep his love only for ourselves, we will wither up in the sin of selfishness. If we share his love, we will grow in life and love.
