The phrase “god of this age” refers to Satan, as mentioned in 2 Corinthians 4:4. This verse explains that Satan has blinded the minds of unbelievers, preventing them from seeing the light of the gospel of Christ, who is the image of God12.
Satan is also called the “prince of this world” in other parts of the Bible, such as John chapter 12 verse 31 and John 16, verse 112. Despite these titles, it’s important to note that Satan is not equal to God. He is a created being and his power is limited.
