'To the end' does not mean to the end of Jesus' life. To the end does not have a finite, temporal quality here. 'To the end' in Greek means to the end of where love ends, an infinite quality. Strong's says,
It is well-illustrated with the old pirate's telescope, unfolding (extending out) one stage at a time to function at full-strength (capacity effectiveness).So to the end doesn't mean to the end of Jesus life, it means to full extension or furthest capacity. This, of course, is an infinite love, the end of which is only contained in Jesus the finite God-man, who is infinite.
As you go throughout your day, realize that this love was not offered to or lavished on just the disciples, but it's also lavished on you and me. It's given to all who believe. Such love is beyond comprehension, yet we experience it daily.
No matter what you are going through or experiencing, Jesus loves us 'to the end', to the fullest capacity that it is possible to love. What comfort.
