When they entered the city

Peter and John and James and Andrew,

All these devoted themselves with one accord to prayer,

1 pt 4:13-16
Beloved:
Rejoice to the extent that you share in the sufferings of Christ,
so that when his glory is revealed
you may also rejoice exultantly.
If you are insulted for the name of Christ, blessed are you,
for the Spirit of glory and of God rests upon you.
But let no one among you be made to suffer
as a murderer, a thief, an evildoer, or as an intriguer.
But whoever is made to suffer as a Christian should not be ashamed
but glorify God because of the name.
jn 17:1-11a
Jesus raised his eyes to heaven and said,
"Father, the hour has come.
Give glory to your son, so that your son may glorify you,
just as you gave him authority over all people,
so that your son may give eternal life to all you gave him.
Now this is eternal life,
that they should know you, the only true God,
and the one whom you sent, Jesus Christ.
I glorified you on earth
by accomplishing the work that you gave me to do.
Now glorify me, Father, with you,
with the glory that I had with you before the world began.
"I revealed your name to those whom you gave me out of the world.
They belonged to you, and you gave them to me,
and they have kept your word.
Now they know that everything you gave me is from you,
because the words you gave to me I have given to them,
and they accepted them and truly understood that I came from you,
and they have believed that you sent me.
I pray for them.
I do not pray for the world but for the ones you have given me,
because they are yours, and everything of mine is yours
and everything of yours is mine,
and I have been glorified in them.
And now I will no longer be in the world,
but they are in the world, while I am coming to you."
