Should we pray to God and ask him for a parking space? Or that the city bus arrive soon? The author of Hebrews asks for rapid transport:
I especially ask you to pray that I may be restored to you very soon.
Hebrews 13:19 NET
Many prayer requests are made in order to satisfy selfishness. The author thinks in terms of edifying his brethren. After writing his letter, he also wants to encourage them in their faith personally. He prays, and asks his readers to pray, to this end.
Every prayer made to accomplish the will of God will have an answer.
