That is my understanding of "as onto the Lord": "Wives, submit yourselves unto your own husbands, as unto the Lord." We have a covenant relationship with God. A covenant has conditions. If we do our part then we can be sure that God will do His part. In this case we are told that the wife is to submit to her husband, but this is qualified with "as unto the Lord". So what is your understanding of this passage?
If the husband is in rebellion and not following God then why should the wife follow him in his rebellion and do something that God tells us not to do? We are not to live life in the flesh, we are to live in the Spirit. Galatians 5 "16 So I say, walk by the Spirit, and you will not gratify the desires of the flesh. 17
For the flesh craves what is contrary to the Spirit, and the Spirit what is contrary to the flesh.They are opposed to one another, so that you do not do what you want. "
This is the job of the husband to follow God and to help the wife to be all that God wants her to be.
