In graphic language, God demonstrated that covenant breakers with men become covenant breakers with God. Where the spirit of treachery is in human relationships, in other words, it will be in one's relationship with God. Divorce demonstrates hardness of heart. To this could be added the witness of many marriage counselors. The underlying problem in marital conflict is self-centeredness.
Divorce is but the continued expression of a hard heart.
It takes humility, love, and brokenness to resolve marriage problems and to experience the oneness intended in marriage. Divorce hurts one's partner. Treachery is a betrayal word. Where there is betrayal, there is hurt. Trust and loyalty are intrinsically bound up in love, and divorce knifes mercilessly through those bonds causing hurt.
