The fourth-century theologian Athanasius wrote: “When a portrait is spoiled, the only way to renew it is for the subject to come back to the studio and sit for the artist all over again. That is why Christ came—to make it possible for the divine image in man to be re-created.”
The word “Gospel” comes from the Greek word for “good news” and is a term that is used to refer to the message of Christianity.
The Gospel in a nutshell is that Jesus Christ came into the world to save sinners (a concept that comes from 1 Timothy 1:15). An accurate presentation of the Gospel must include the life, death, resurrection, and ascension of Jesus. In His life, Jesus taught His disciples in both word and deed (Mark 10:1; 1 Peter 2:21); in His death, He was the once-for-all sacrifice for our sins (Hebrews 9:28); in His resurrection, He defeated the power of sin and Satan (1 Corinthians 15:17); in His ascension, He sat down at the right hand of God where He now intercedes for us (Romans 8:34).
All four of those points are essential to understanding the work that Jesus performed in making salvation available to sinners.
