Who is to preach the Gospel? Is it the one who gets paid to preach the Gospel? Is it the one that is ordained and holds an office that some call Minister of the Word and others call Teaching Elder?
Can un-ordained men preach? How about women? How about 5 year olds or teenagers?
The answer, of course, is no and yes.
Does that sound like a postmodern answer to you? Well, it is quite ancient:
Acts 8:4-5 Now those who were scattered went about preaching the word. Philip went down to the city of Samaria and preached to them the Christ.
Verse 4 says that those who were scattered were preaching the word. Our English translation for preach is from the Greek word which means 'spreading the good news' or 'gossiping the Gospel'. This is the duty of all whose hearts have been changed by the Lord Jesus Christ. A converted heart overflows with the love of God and there is a desire to 'preach' Christ to all who are around. This means that the un-ordained layman, the old church lady, the little kids, the teens.... all who have been redeemed have this obligation to preach, or gossip the good news of Jesus Christ and his death for sinners.
Verse 5 is a different story. This verse uses a different word for preach. The word is the same word as 'herald'. In verse 5 we see Philip preaching the Gospel in a commissioned, ordained, set apart for public ministry way. This is heralding of the good news that Jesus Christ died for sinners! All who are ordained to the task of Minister of the Gospel, or Teaching Elder, has this responsibility. Preach Christ crucified!
Remember though. None of us are off the hook. We are all verse 4 preachers or verse 5 preachers! Now preach Christ to those who are lost.
