The Christian message is often referred to as the "Gospel," which means "good news." Specifically, it is the good news about Jesus—who He is, what He has done, and what He offers. Essentially, the message is that Jesus was God in the flesh, that He came into the world to reconcile humanity to Himself, and that his salvation is freely offered to each person who will respond in faith. The Gospel message explains that salvation is only possible through the Crucifixion and Resurrection of Jesus. Through his sacrifice, Jesus paid the price for our sinfulness (rebellion against God), thus offering us forgiveness. Then through his Resurrection He conquered death, removing it as the penalty for our sin and replacing it with the offer of eternal life that is only available from Him to all those that place their faith in Him.
