Paul knew this would be his last visit to the churches in Asia. He also knew that Jerusalem would not be easy for him. His friends prophesied that he would be arrested in Jerusalem. They begged him not to continue, but he did anyway:
Acts 20:22-24 And now I am bound by the Spirit to go to Jerusalem. I don’t know what awaits me, except that the Holy Spirit tells me in city after city that jail and suffering lie ahead. But my life is worth nothing to me unless I use it for finishing the work assigned me by the Lord Jesus—the work of telling others the Good News about the wonderful grace of God.
