Jesus said to his disciples:
"Peace I leave with you; my peace I give to you.
Not as the world gives do I give it to you.
Do not let your hearts be troubled or afraid.
You heard me tell you,
'I am going away and I will come back to you.'
If you loved me,
you would rejoice that I am going to the Father;
for the Father is greater than I.
And now I have told you this before it happens,
so that when it happens you may believe. (John 14:28-31)
