What other proof can be found of Christ's love?

John 15:13 Greater love hath no man than this, that a man lay down his life for his friends. 

I could stop typing this post right now and it would be
enough,
because Christ's Atonement is
enough. 
God gave His only begotten son that we might live with Him again.  Christ gave his life for us, that if we love God and live the Commandments...it would be
enough. 

Although Christ's death testifies of his love for us, his life seals that testimony.  His death would never have had the impact on us if he hadn't been an example of love, service, sacrifice, obedience, strength, virtue, forgiveness, humility, and countless other attributes during his life. 

We are taught the greatest of these is love....

“Master, which is the great commandment in the law?
“Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
“This is the first and great commandment.
“And the second is like unto it, Thou shalt love thy neighbour as thyself.
“On these two commandments hang all the law and the prophets.” (Matt. 22:35–40.)

Off the top of my head, the stories of Jesus that teach us love include;

blessing the children,

raising the dead,

feeding the five thousand,

casting out demons,

healing the lepers...the blind...the sick,

cleansing the temple,

washing the feet of his Apostles,

forgiving those who did him harm,

asking his beloved disciple to care for his mother,

returning in his resurrected form to show that he had overcome death.

Maybe a better question to ask would be -
What proof can be found that Christ didn't love us?
I can think of none.
