The most likely author of Romans 1:20 is the Apostle Paul. Evangelical Christians believe that Paul was chosen by Jesus to be an apostle and wrote many of the books in the New Testament, including the book of Romans. They believe that the Bible is the inspired word of God and that the authors were guided by the Holy Spirit as they wrote. Therefore, Romans 1:20 is considered to be a divinely inspired statement about the evidence of God’s existence in the natural world. Evangelicals believe that Paul’s writings, including Romans 1:20, are authoritative and should be studied and applied to their lives. They see this verse as a powerful reminder of God’s presence and power in the created world, and a call to recognize and worship Him as the Creator.
