The satanic powers understand that “the sexually immoral person sins against his own body” (1 Cor. 6:18). They understand that the pornographic act severs a one-flesh marriage union at the very point of intimate connectedness and instead joins Christ, spiritually, to an electronic prostitute (1 Cor. 6:16). They also know that those who unrepentantly practice such things “will not inherit the kingdom of God” (1 Cor. 6:9-10).
