The Gospels record Christ's ministry to the four groups of people then and now in the world. The Jews who loved the Scriptures and the prophecies of God. They would only listen to one of their own. So Matthew speaks to the Jews and the deeply religious of our day.
Mark spoke to the Romans. These were the leaders and leadership and action impressed them. They knew nothing of Scriptures but everything of power. So to this group comes the action-packed Gospel of the powerful ministry of Christ. Mark uses the word and 1,375 times to tie together the endless actions of Christ. Like our modern successful business men and women, they want a God who can powerfully meet their deepest needs.
Luke was a Greek speaking to the Greeks. The Greeks loved culture, beauty and ideas. Happiness could be found in the pursuit of truth. Luke fills his book with insights, interviews, songs, and details that fascinate the inquiring mind. So today the truth seekers find Jesus in Luke!
John wrote to everyone, because everyone needs to meet God and only Jesus can reveal Him. In this book we meet an absolutely powerful God in human flesh who controls and rules the Universe He created. So the best known verse is the best of all offer that God loves all and offers all - His Son as their only hope!
