Romans 1:16-17 ESV ( The Righteous Shall Live by Faith )
For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. 17 For in it the righteousness of God is revealed from faith for faith, as it is written, “The righteous shall live by faith.”
1 Corinthians 1:18 NLT ( Christ the Wisdom and Power of God [ESV] )
The message of the cross is foolish to those who are headed for destruction! But we who are being saved know it is the very power of God.
1 Corinthians 2:1-5 NASB2020 ( My Message: Jesus Christ on the Cross [ERV] )
And when I came to you, brothers and sisters, I did not come as someone superior in speaking ability or wisdom, as I proclaimed to you the testimony of God. 2 For I determined to know nothing among you except Jesus Christ, and Him crucified. 3 I also was with you in weakness and fear, and in great trembling, 4 and my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power, 5 so that your faith would not rest on the wisdom of mankind, but on the power of God.
