The Middle East, the Islamic countries of today, mainly there were Christians.
All who received the gospel message from Christ during his time were preachers of the gospel. (John 4: 7-26; 9: 1-12; Luke 19: 1-10). The early Christians were the result of the teachings of the Apostles. Their lifestyle was evangelistic. When the gospel message was filled with their thoughts, attitudes and lifestyles, their human relationships fell in love. As a result, the number of believers began to increase. (Acts 2:47). They shared their faith and life experiences with the new community; He preached the gospel boldly. (Acts 4:31).
Christ was the head of the church. There was no difference between the great and the small. They were preaching the gospel with a single heart and in a perfect heart. Later, church leaders and clerical leadership appointed their leader. Faith is formed into a religion. There were many false beliefs in the church. Religious leaders argued that God is one and the Trinity. It began with image making and idolatry. Devotion to the mother was the worship of the mother. This has confused many people. The fanatics were coming one after the other. The church founded by Christ was transformed into another church. In this context, many Protestants were formed in the church itself. Believers went to the faith they felt was right. The vast majority of believers went to Islam.
If Christians were to worship the One God in spirit and truth, Islam would not have existed and Islam would have no relevance. The Christians in the Middle East were working Christians. They would work for the world!
