The gospel of Luke was written by Luke (Ellis, 2003). It presents Jesus Christ as the son of God and a savior who comes to save all men. In the book of Luke 4:16-21, Jesus reads the book of prophet Isaiah where it is written that he is sent to release the captives, heal the sick and setting liberty to the oppressed, and he states that the scripture written by Isaiah has been fulfilled. At some instances, Jesus gives promises which were later fulfilled. During the last supper, he promises that one of his disciples will betray him, Peter will deny him, and he will be crucified and on the third day, he will rise from the dead. All these promises are fulfilled in Luke 24:1 when Jesus rises from the dead.
The Gospel of Luke shows universality to Christians as it gives a vivid description of Jesus as the Savior to all people including the Gentiles, Samaritans, and Jews; publican and religious leaders; despised and respectable and this shows that Christians should preach the gospel to all people. Most of the gospel of Luke is based on parables which Jesus uses to teach his disciples about what is good and what is not.
The reversal of fortune is communicated in proverbial wisdom in Luke 14: 11 that those who exalt themselves will be humble and those that humble themselves will be exalted. He teaches on the parable of the rich man and the Lazarus, showing that the afterlife is determined by how people live on earth. The rich on earth becomes the poor in heaven, and the poor on earth becomes the rich in heaven. Therefore, Christians should yearn for poverty because richness in the kingdom of God is theirs (Lehtipuu, 2007).
