1 Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, 2 by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain. (1 Corinthians 15:1-2 NASB)
The Apostle Paul defined the gospel for us throughout his writings in the New Testament. In these dark spiritual times in which people believe their opinions and feelings are consistent with “truth” it is vital that we know God’s truth and make it known to all who will hear. I would like to start in 1 Corinthians 15:1-11. I placed vv1-2 at the top of this post. In v1 he tells us that he is going to define the Gospel (εὐαγγέλιον) as a process. In this process, the Gospel must be proclaimed (εὐηγγελισάμην) and through this some who hear it will receive it and it is their very foundation. I pray that you noticed the similarities between the two Greek words above. The word εὐαγγέλιον is Greek for “a good message” or “the good news.” The word εὐηγγελισάμην literally means “announce good news.” It is the word from which we get our English word “evangelize.” Notice also that those who hear the good news and are saved by it also stand (ἑστήκατε) within it because it is their foundation. This Greek word means “you stand.” They abide in the covenant of the Gospel because it is now their foundation.
