Yes,
I have a story. It's a Bible story. Actually there's 2.
There was a man named Hosea. God actually told him to marry a whore (prostitute).
He did what God told him, and they had children together. Of course, over time, she left him for other MEN. Not just one man, but MANY. However, faithful Hosea prayed for her constantly. The Bible says that God used Hosea and his wife as a sign unto the people of Israel at that time. The Lord used his relationship to symbolize God's relationship with the people of Israel. The people forsook God to serve other gods. Many gods. Idols, graven images, and even devils! It was spiritual adultery.
As time went on, Gomer (Hosea's wife) was still out and about doing her thing with other men. But look at what God says to Hosea...
"5 For their mother hath played the harlot: she that conceived them hath done shamefully: for she said, I will go after my lovers, that give me my bread and my water, my wool and my flax, mine oil and my drink.
6 Therefore, behold, I will hedge up thy way with thorns, and make a wall, that she shall not find her paths.
7 And she shall follow after her lovers, but she shall not overtake them; and she shall seek them, but shall not find them: then shall she say, I will go and return to my first husband; for then was it better with me than now." - Hosea 2:5-7
God actually fought AGAINST Gomer! He brought her so low that she actually decided to leave her current husband for her first husband, Hosea! Notice she said, I will return unto my FIRST husband.
And during all of this time, faithful Hosea just kept busy raising the kids, praying for his wife, and preaching to the people of Israel. Once God had humbled Gomer to the point of return, look at what he told Hosea:
"1 Then said the LORD unto me, Go yet, love a woman beloved of her friend, yet an adulteress, according to the love of the LORD toward the children of Israel, who look to other gods, and love flagons of wine.
2 So I bought her to me for fifteen pieces of silver, and for an homer of barley, and an half homer of barley:
3 And I said unto her, Thou shalt abide for me many days; thou shalt not play the harlot, and thou shalt not be for another man: so will I also be for thee." - Hosea 3:1-3
Hosea, bought her back! After all that she had done to him, he remained faithful (for who knows how long), and stayed single all that time, and he still took her back when God brought her to her senses.
Another story I have is also from the Bible.
God called himself the husband of the nation of Israel. He was faithful, loving, and cared for that nation like a loving husband cared for his wife. God gave rain, harvest, and plenty of lush vegatation for the people, providing very well for his nation that he loved. Yet, the nation of Israel became unfaithful to God. They forsook him and began to whore themselves out to other gods, even devils! They worshipped stone images and idols that cannot speak or do anything! God was extremely furious and jealous. But look at what he says:
"1 They say, If a man put away his wife, and she go from him, and become another man's, shall he return unto her again? shall not that land be greatly polluted? but thou hast played the harlot with many lovers; yet return again to me, saith the LORD." - Jeremiah 3:1
The story does not end there. God actually left heaven, put on human flesh, received the name Jesus Christ, and carried a cross willingly for his beloved bride and allowed himself to be crucified for her. Though she beat him, spat on him, and nailed him to a cross, his love for his people was so great that he did it willingly. 3 days later, he rose from the dead. Ever since, the people he died for and loved so much have turned their whole hearts to him (though not all). Reading the first couple chapters of the book of Acts, you can see that within a matter of 1 day, 5 thousand people turned to the Lord!
Patience and persistance pays off. And never forget to do good to those who hate you. Never repay evil for evil. Be not overcome with evil, but overcome evil with good.
