For one thing, Christ would never ask the church to sin. Husbands may ask their wives' to sin. I believe it is okay to disobey your husband if he asks you to do something that is clearly against Scripture such as participating in pornography, a threesome, open marriage, etc.
Scripture teaches, Wives, in the same way submit yourselves to your own husbands so that, if any of them do not believe the word, they may be won over without words by the behavior of their wives, when they see the purity and reverence of your lives. {I Peter 3:1,2}
Our husbands will not be won by impure behavior even if he asks you to do it. God is our highest authority so we must obey God rather than man, which includes our husbands, and live pure and reverent lives as He has commanded us to do.
In the same way, we are commanded to obey our government, but if it asks us to abort our babies, we would not obey.
However, wives are commanded to obey their husbands in everything so this must be your goal. Most husbands will never ask their wives to sin so we should not use the "what ifs" to excuse disobeying our husbands.
Sunshine Mary recently made this comment on one of her posts, "We do not need to stand in judgment of our husbands' instructions to us. Almost always their instructions will be good ones, but even if on occasion they are not good, still we are commanded to obey them without fear, and to trust in God, the only One who never fails. Sisters, God will not bless your rebellion against your husband, whatever the reason, but He will bless your submission and obedience."
