“They saw that God had given me the task of preaching the gospel to the Gentiles, just as he had given Peter the task of preaching the gospel to the Jews”. 

Gal 2:7 GNB 

Communication always takes place within a context, a specific situation and often that situation tends to influence the way the facts or opinions get communicated. Communication experts say that some methods of communication are “hot” and others “cold”. Television is “hot” but the newspaper is “cold”. A politician may shout and gesticulate at a political meeting. In a television studio he would speak as if he were having a quiet chat to just one person. 
Whilst Peter and Paul were bringing out various elements of the message about Jesus, the core of their two presentations was basically the same. It was the centrality of the fact that Jesus was God incarnate, he had taught and healed many people and died on the cross. God had raised him from the dead and sent the Holy Spirit to be with his people forever. People must now repent of their sins, accept Jesus Christ as Lord, Saviour and Messiah, reform their lifestyles and pattern their way of life on Jesus himself. Christ would return and bring history to its conclusion. Jesus was the physical and human manifestation of God the Father’s love for all people. 
That is still the core of the gospel. Anything that deviates far from this message needs to be examined critically and carefully. Of course it needs to be related to the world situation today, and to the needs of individuals. This core should be the key for any communicator to relate and interpret the Bible and its many sub-messages. It should apply to everyday life anywhere in the world. 

Lord, let the gospel be heard everywhere.
