Romans 1:16-20 (English Standard Version)

The Righteous Shall Live by Faith
 16For 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. 17For in it the righteousness of God is revealed from faith for faith, as it is written, "The righteous shall live by faith."
God’s Wrath on Unrighteousness
 18For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. 19For what can be known about God is plain to them, because God has shown it to them. 20For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
