Romans 1 explains that God has made himself known to everyone through creation, but many people have rejected him and have instead followed their own desires. Paul introduces himself and greets the Roman Christians to whom he is writing. He also stresses the importance of faith and obedience to God's will, and warns against idolatry and immorality. Paul explains that all people, both Jews and Gentiles, have sinned and are in need of salvation through faith in Jesus Christ. Paul also argues that God's wrath is revealed against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness. Paul illustrates this in how men and women have exchanged natural desires for unnatural desires in the same way people have exchange the truth of God for a lie. Ultimately, the chapter emphasizes the importance of maintaining a relationship with God and following His plan for our lives.
