but let it be the hidden person of the heart, with the imperishable quality of a gentle and quiet spirit, which is precious in the sight of God. For in this way in former times the holy women also, who hoped in God, used to adorn themselves, being submissive to their own husbands; just as Sarah obeyed Abraham, calling him lord, and you have become her children if you do what is right without being frightened by any fear.
1 Peter 3:4-6 (NASB)
Be committed to one another, not out of fear or by force, but from a willing heart, and in obedience to the command of God, from a desire to do well and to please Him.
