We love because he first loved us.
1 John 4:19
We learned how to love and be loved because he first showed his love to us, which he completed in the cross. I always remember this song I used to hear about God's love in my native language.
'As you complete the meaning of the word love in this world by giving your life, I understand that love is suffering, I see that love is death.
Love turns into sacrifice, it takes blood, love is fulfilled in the cross, love turns into Holy Mass.'
It's his love that is being expressed by us. So, show your love for others, ultimately being God's love for everyone.
