The Apostle Paul notably quipped:
“I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes…” (Romans 1.16)
The “gospel” is the message – the “Good News” – about the life, death, and resurrection of Jesus and of the Kingdom in and over which he reigns.. Paul is saying that the message has power – life-giving and life-transforming power to all who believe the message. Bible scholars will point out that the construct of the Greek word for “believe”, and the context within the sentence, express that the word carries a connotation of “on-going belief”. In other words, the aspect of salvation that we call “justification” occurs the moment one believes; and the on-going effect of salvation, the process of salvation we call “sanctification” occurs by the same power, and by on-going belief in the same message.
Properly speaking, the gospel message is about Jesus; but the fruit of the gospel becomes evident in those who are believing. The gospel is the power to change us. Certain things become true because of the gospel – because of Jesus. Here are a handful of passages describing what is now true because of the gospel:
John 5.24 – Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
2 Corinthians 5.19 – In Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation.
Romans 5.1 – Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ.
Romans 8.1 – There is therefore now no condemnation for those who are in Christ Jesus.
Romans 8.2 – For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death.
Ephesians 1.5 – …he predestined us for adoption to himself as sons through Jesus Christ, according to the purpose of his will…
Ephesians 3.16-19 – …that according to the riches of his glory he may grant you to be strengthened with power through his Spirit in your inner being, 17 so that Christ may dwell in your hearts through faith—that you, being rooted and grounded in love, 18 may have strength to comprehend with all the saints what is the breadth and length and height and depth, 19 and to know the love of Christ that surpasses knowledge, that you may be filled with all the fullness of God.
Colossians 3.1-4 – If then you have been raised with Christ, seek the things that are above, where Christ is, seated at the right hand of God. 2 Set your minds on things that are above, not on things that are on earth. 3 For you have died, and your life is hidden with Christ in God. 4 When Christ who is your[a] life appears, then you also will appear with him in glory.
1 John 4.7-12 – 7 Beloved, let us love one another, for love is from God, and whoever loves has been born of God and knows God. 8 Anyone who does not love does not know God, because God is love. 9 In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. 10 In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins. 11 Beloved, if God so loved us, we also ought to love one another.12 No one has ever seen God; if we love one another, God abides in us and his love is perfected in us.
Revelation 12.10-11 – 10 And I heard a loud voice in heaven, saying, “Now the salvation and the power and the kingdom of our God and the authority of his Christ have come, for the accuser of our brothers has been thrown down, who accuses them day and night before our God. 11 And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death.
