Satan has erected many walls to keep Arabs from being open to the Gospel. Political and national barriers have been created between Christians and Arabs throughout history. The crusades of the 11th and 13th centuries developed deep and lasting wounds of bitterness.
First of all worship God for who He is. Thank Him for his great love, mercy, and compassion. Declare His sovereignty and majesty. Secondly, pray for the Church worldwide - especially in the Arab nations. Pray for strength, courage, determination, boldness, and protection for the believers there. Thirdly, pray for the lost. Many Arabs are coming to the Lord through dreams and visions. Pray for a divine visitation for key Arab leaders, that they might see Jesus for who He really is. Pray for mercy and peace for the nations that are in turmoil, and the massive number of refugees caught in various struggles.
Remember, the fervent prayer of the righteous avails much!
