Jesus said in Mark 10:9 that what God has joined together, let no man will separate. Jesus was of course referring to the union between a man and a woman. And, it is so that there are often attacks on the union between a man and his wife, because marriage represents the mystical union between Jesus and His church.
When Abraham was due to enter Egypt, he feared that his wife Sarah would be taken from him in account of her beauty. Such was her beauty, that he further feared for his life at the hands of the men of Egypt. Driven by fear, Abraham convinced Sarah to say that she was his sister. As it happened she was taken into the home of Pharaoh with the intent of making her his bride.
Genesis 12:17 recounts the Lord’s response to this act by Pharaoh:
Sarah was subsequently released with a blessing to Abraham. We learn that God is true to His word. He has declared that what He has put together, he will not let others set apart. Bear in mind that Pharaoh, was arguably the most powerful and influential ruler of the day, and he had to bow to the word of God.
The Lord God, delights in the sacred union of marriage. If our hearts are set on the preservation of that union, He will turn the world upside down for us. If your relationship is under threat, invoke the promise of God for your union, and then, watch Him work to preserve His promise and your union.
