What could more emphatically prove His love?

What could more emphatically prove His love?
(Newman Hall, "The Voice of Jesus in the Storm")

"Christ died for the ungodly!" Romans 5:6 

"Christ loved us and gave Himself up for us as a fragrant offering and sacrifice to God!" Ephesians 5:2 

What could more emphatically prove His love — than coming to this world of sorrow and sin to suffer and die for us, when we were His enemies? He left . . .
  His habitation in glory — for the foul stable,
  the homage of angels — for the insults of men,
  the smile of His Father — for the temptations of the devil,
  the raptures of Heaven — for the groans of Gethsemane,
  the splendors of His heavenly throne — for the ignominy of the cruel cross,
  the brightness of the celestial glory — for the darkness of the tomb!

And why was this? It was love that prompted His sin-atoning sacrifice. Love to the undeserving, to the rebellious, to those who then crucified Him, and to those who now pierce Him by their sins! 

"May you experience the love of Christ, though it is too great to understand fully!" Ephesians 3:19
