Charles Spurgeon Commentary 1 Peter 3:1-2

"In like manner, ye wives, [be] in subjection to your won husbands; that, even if any obey not the word, they may without the word be gained by the behavior of their wives; beholding your chaste behavior [coupled] with fear." — 1 Peter 3:1-2 (ASV)

Likewise, you wives, be in subjection to your own husbands; that, if any do not obey the word, they also may without the word be won by the conversation of the wives; while they behold your chaste conversation coupled with fear.

Could any men be won to Christ without the Word? Yes, it was indeed so in the apostle's day. When they refused to attend the small Christian meetings that were being held, and so could not hear what was said there, yet, at home, they saw the change that the gospel of Christ had worked in their wives, and they said, "She is quite different from what she used to be. Certainly, she is a far better wife than any unbelieving woman is; there must be something in this religion that can make such a change as that." In this way, without the Word, many of them were won to Christ by the godly conduct of their wives.
