Acts21,17 When we arrived at Jerusalem, the brothers received us warmly. > Sounds almost like it did not was so nice - a warm welcome - hey, good to se you ...
18 The next day Paul and the rest of us went to see James, and all the elders were present. > James is now the men! Where are the Apostels?
19 Paul greeted them and reported in detail what God had done among the Gentiles through his ministry.  > He had a lot to say. How most they have felt, since  - at least we - do not know anything what they in Jerusalem did - :What is wrong with my heart, that i think like this.
20 When they heard this, they praised God. Then they said to Paul: You see, brother, how many thousands of Jews have believed, and all of them are zealous for the law. > Am i zealous for God?
21 They have been informed that you teach all the Jews who live among the Gentiles to turn away from Moses, telling them not to circumcise their children or live according to our customs. > immediately some political issues are brought up. - Praising God and make some peace between people who are not close to Paul but heard things about him and Paul
22 What shall we do? They will certainly hear that you have come, > They are at least humble in asking.
23 so do what we tell you. > Funny i thought they will listen to Paul, what he think he should do. 
There are four men with us who have made a vow.
24 Take these men, join in their purification rites and pay their expenses>WOW, even many is needed... , so that they can have their heads shaved. Then everybody will know there is no truth in these reports about you, but that you yourself are living in obedience to the law. > ???
25 As for the Gentile believers, we have written to them our decision that they should abstain from food sacrificed to idols, from blood, from the meat of strangled animals and from sexual immorality. > Eating was a big issue. And sex. 
26 The next day Paul took the men and purified himself along with them. > No word from Paul is recorded. He basically did what he was told. Then he went to the temple to give notice of the date when the days of purification would end and the offering would be made for each of them.>

For what am i zealous today? What is robing my sleep? What drives me? Why would i endure and what would that be?

God please help me to be zealous for you!

Paul reports great things happend in his mission.
The other come again with political matters. Somehow to keep peace. Paul is not arguing about it. Paul submit to all of that. He is even paying for others.
What a humble heart.
He is just obeying.
He must have ben completely in peace!
God help me to have peace about what ever is hitting and hurting me.
Help me, that i never think i need to fight for me.
The i always know, you fight for me.
