This was to be an important message. "Who has believed our report? and to whom is the arm of the Lord revealed" (Isaiah 53:1) This is the question down through the centuries. Isaiah, the prophet spoke it over seven hundred years before the appearance of Jesus on the world stage. Paul, an apostle, takes it further and adds, "How then shall they call on him in whom they have not heard? and how shall they hear without a preacher?" (Romans 10:14)
In Isaiah, the prophet is testifying to the coming savior of the world. Yes, centuries before Jesus ever appeared on this earth, the message that he was coming was carried to any who would listen. When Jesus did come, the Jews rejected him. Then, after his death and resurrection, Christ turned to the gentiles.
Paul enters the scene and becomes the apostle to the gentiles. Like Pastor Josh said, "Thank God, the gentiles believed." Still there are many who have not believed the report. Buildings are filled for all kinds of events and occasions. And, yet, the churches around the country have plenty of room for those who need to come and listen to God's chosen proclaim the message of salvation.
Isaiah spoke, Paul spoke, and many, many more down though the centuries have spoken. Still, God calls those to be preachers to tell the world about salvation. He hasn't given up on the human race. Go to the church just around the corner. Attend it. And listen for God calling all who will listen. Called preachers calling the lost to call on God to receive the message of salvation.
