There is research that shows peoples first criterion for choosing a church to attend is the message delivered in the church. It means that they want to attend a church where the message preached is good. What then are good messages? It is a good message that properly reveals Gods heart and will and that leads people to the way of salvation and eternal life. As good food makes us healthy, good messages allow for you to maintain a healthy life in spirit and lead you to salvation.
"But the word of the Lord endures forever. And this is the word which was preached to you" (1 Peter 1:25).
