In this website the author refers to “this evil world” in 2 Corinthians 4:4. The word is “age”, not world, as Satan is the God of this age (time outside the realm of eternity) and God is the God of eternity (the spiritual realm outside of time and this age).

Adam’s sin cursed the earth. The Lord Jesus’ sacrifice on our behalf, for our sins and sicknesses enabled us to receive back the authority Adam gave to the devil, but the Lord Jesus took back from the devil and gave to us again. We have authority once again. (Emphasis added)
Romans 5:17 For if because of one man’s trespass (lapse, offense) death reigned through that one, much more surely will those who receive [God’s] overflowing grace (unmerited favor) and the free gift of righteousness [putting them into right standing with Himself] reign as kings in life through the one Man Jesus Christ (the Messiah, the Anointed One).” (Emphasis added)
