Jesus said in New Revised Standard version of John 15:12-15
This is my commandment, that you love one another as I have loved you. No one has greater love than this, to lay down one’s life for one’s friends. You are my friends if you do what I command you. I do not call you servants any longer, because the servant does not know what the master is doing; but I have called you friends, because I have made known to you everything that I have heard from my Father.
NRSV John 16:7, 22 Nevertheless I tell you the truth: it is to your advantage that I go away, for if I do not go away, the Advocate will not come to you; but if I go, I will send him to you.
So you have pain now; but I will see you again, and your hearts will rejoice, and no one will take your joy from you.

“Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles. And let us run with perseverance the race marked out for us, fixing our eyes on Jesus, the pioneer and perfecter of faith. For the joy set before him he endured the cross, scorning its shame, and sat down at the right hand of the throne of God. Consider Him who endured such opposition from sinners, so that you will not grow weary and lose heart.” Hebrews 12:1-3 NIV
