Today the Catholic Church commemorates the Passion of the Lord.
In His passion, though -- in His suffering and death by crucifixion at the hands of men with evil in their hearts -- we also see the action of the Lord.
Jesus died in order that we might have eternal life. This is an act -- a freely chosen action -- of love.
Jesus' love for us comes from the same source everything else Jesus has comes from: from the Father. Jesus is the image of the invisible God. The image of Jesus on the cross is an image of the Father's love for us.
At the end, Jesus returns everything He has, including the love for us which held Him to the cross, to His Father. And His Father accepts it all. The love for us which we marvel at today, the love unto death centuries ago, is the same love with which the Father regards us, today and eternally.
