This is the only way in which we are able to love and live in the manner in which a spirit filled Christian should. Paul gives more details in Ephesians 4. We are not to live our lives according to the old ways when we lived in the flesh. Let me get very practical here. Families are losing their focus, and domestic violence, abuse, and emotional dysfunctions have gone vertical.
Second marriages fare no better than first timers.
Moreover, if you are living in a dysfunctional relationship with another person, it's because you have a dysfunctional relationship with yourself. You have no idea what manner of hell my partner brings into my life. But I do know it takes two to tango, and if you are able to change yourself, if you are able to create a different lifestyle and environment in which relationship takes place, if you are able to regain your own power and reclaim your right to dignity and respect, then your partner is going to be seriously affected. You can't control your partner. You can't make changes for your partner.
