In all honesty I do not think there is a scripture that says literaly for wives to love their husbands. Yet all christians are expected to walk in love, and if a woman desires to submit to her husband she would defenetely love her husband unconditionaly. If a husband loves his wife like Jesus does the church that means he is willing to lay his agenda down in that marriage. Now I ask you if you had a love in your life like that wouldn’t you love the giver of such love?(BTW there is scriptures for husbands to submit to their wives too).
Please note I am sharing what I believe to be true if I am out in left field I pray that the Lord reveal the truth to me. However I also believe sincerely I am correct.
Pray about it and you will corner the truth personaly concerning this matter. GBU friend
