In this passage Paul tells the Corinthians he wanted to present them as a pure virgin to their husband, Christ. He was afraid that as Eve was deceived, so the Corinthians would be led astray from their pure and sincere devotion to Christ. He was concerned that they were being receptive to a different Jesus, a different spirit, and a different gospel. It is the same issues our culture struggles with today. Until Jesus returns there will be false teachers trying to lead us away from the biblical Jesus to faith in ourselves.
