First, submission is not simply something for wives. The Bible instructs us about other relationships that involve submission. Slaves are commanded to submit to their masters. Children are commanded to submit to their parents. All people are commanded to submit to the governing authorities. Christians are commanded to submit themselves to the leadership of the local church. And wives are commanded to submit to their husbands.
Second, submission does not imply inferiority. That is the feminist argument. They argue that submission degrades a woman. However, consider Christ. In value and worth, He was certainly superior to his earthly parents, Mary and Joseph. Yet in Luke 2:51, we see that He submitted Himself to them.
Third, submission does not mean that the woman is stupid. It does not imply a kind of slavery where the woman is little more than a doormat. Submission expects you to bring everything God made you to be to the marriage. As God has given you grace, bring it. As God has given you wisdom, bring it. Your whole experience, intuition, education and gifts are to be brought to the marriage. Do not truncate what God has entrusted to you. Submission is not shutting these things off.
Submission does not mean that you can't take initiative. But when you take an action, you don't take one you know which would oppose the will and pleasure of your husband. Submission does not mean giving up independent thoughts. When you submit to Christ, you do it will all your being.
Submission does not mean silence. Scripture is not commanding you to be blind to your husband's faults. You don't need to keep quiet about his sin. You don't need to restrain yourself from giving counsel. In fact, a wise husband will seek the counsel of His wife. If God has allowed you to see a potential problem, submission does not mean you have to grin and bear it.
Fourth, submission never means sinning for your husband. Consider the story of Ananias and Saphira. Do not join in any person's sin. Always obey God rather than men. Submission never expects sin. However, if you refuse the will if your husband, you better make sure it's sin. Do not say, "I think continuing to sink money into our Dodge Neon is a sin." The occasions would involve issues of conscience. Hopefully, the husband will not want to violate his wife's conscience.
