Paul wrote to the Galatians how astonished he was that they so quickly departed from the gospel that they were taught. Paul wrote to the Corinthian church that he wanted them to only know Christ and him crucified. Paul praised the church at Philippi for being partners with him in the gospel. And in what I think is the most obvious lesson of the importance of the gospel, in Mark chp. 1 Jesus preaches his first sermon, telling people to repent and believe the gospel.
Gal 1:6 I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel— 7 not that there is another one, but there are some who trouble you and want to distort the gospel of Christ. 8 But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. 9 As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed.
1 Cor. 2:1 And I, when I came to you, brothers, did not come proclaiming to you the testimony of God with lofty speech or wisdom. 2 For I decided to know nothing among you except Jesus Christ and him crucified.
Phil. 1:3 I thank my God in all my remembrance of you, 4 always in every prayer of mine for you all making my prayer with joy, 5 because of your partnership in the gospel from the first day until now.
Mark 1:14 Now after John was arrested, Jesus came into Galilee, proclaiming the gospel of God, 15 and saying, “The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel.”
Jesus himself gave the example: the gospel is the most important thing that the world needs to hear. His earthly ministry was very short, and he had no time to waste. But in his very first sermon he preached the gospel (Greek for “good news” by the way). Recall the words of the Great Commission: “Go into all the world and preach the gospel to every creature.” His first and last words to an audience was the importance of the gospel.
The Apostle Paul wrote about two-thirds of what we call the New Testament. It is clear on several occassions that he believed sharing the gospel was the most important use of our time and energy. I’ve said this before: If I could talk to every preacher, I would say above all else, “Preach the gospel.” The world needs to hear more than anything else Christians have to say that Jesus saves! He is the way, the truth and the life. God doesn’t just judge the world, he provides escape from judgement. God doesn’t just hand out rules, he provides grace because he knows we will all fail at the rules anyway. Our God is an awesome God, and the only way to come to him is by believing in the Gospel of Jesus Christ. Let’s make that what people see and hear when they listen to Christians or come into our churches, not all the other junk they see and hear and think we are about.
Be the salt, be the light, let’s cut the crap.
