1 Peter 3:7
Likewise, ye husbands, dwell with them according to knowledge, giving honour unto the wife, as unto the weaker vessel, and as being heirs together of the grace of life; that your prayers be not hindered.
Husbands are to live in a manner that is considerate of their wives, showing love, courtesy, and understanding. A man’s attitude toward his wife should recognize the fact that she is a fellow heir of the grace of life. When the man doesn’t follow God’s mandate for marriage, the consequence are that his prayers will be hindered.
