2 Corinthians 11:3

‘But I fear, lest by any means, as the serpent beguiled Eve in his craftiness, your minds should be corrupted from the simplicity and the purity that is toward Christ.'

But he admits that he is afraid, that just as the serpent beguiled Eve by his devilish cleverness and subtlety, so their minds might be being corrupted from the simple purity of laying all their hope in Christ and what He is. He does not want anything to come between them and Christ. He wants no veil on their minds. He wants no extras (1 Corinthians 2:2). Just pure and true faith in Christ.

While he does not say so the implication is that Satan is behind these attempts to delude them, and that the deluders are Satan's instruments (compare 2 Corinthians 11:13).

The reference to Eve may well include the inference that the church is the ‘second or last Eve' as Jesus is the ‘second man', the ‘last Adam', but it is not spelt out. However the close connection with the previous verse suggests it. So the words have in mind that living in this present world is for Christians as a whole a preparation for their presentation to Christ, the One Who is the life-giving spirit (1 Corinthians 15:45; 1 Corinthians 15:47). The new Eve is being prepared for her new ‘Adam'.
