"Many of the single mom's I've met (plenty as I used to manage a domestic violence shelter), are not single by choice, most would go back to whatever man they had."
That has not been my experience both as a husband and as an AFDC Social Caseworker and Eligibility Worker for the County. My first single mom lady by covenant was a divorced EuroAm mother of two who divorced her husband because of his persistent immorality and unfaithfulness. She was a good Baptist, in the choir and active in church fellowship. I wrongfully fled from her when she tried to force me to choose between my interracial kids and her racist dad. She went on and married another.
My second single mother of three, Lua Nguyen, was a Vietnamese refugee who turned prostitute in the Cambodian refugee camps to keep her and her kids from starving to death and from being raped. I disobeyed God by covenanting with her before I was sure she was genuinely saved in Jesus (2 Cor 6:14-7:3; Prov 5:20,21; 1 Kings 11). I left after she threw the Bible in the trash saying Jesus didn't answer her prayers, and when I found she was still prostituting to supplement the family income.
My third single AfroAm mother of three, concubine by covenant, was abandoned by the fathers, probably because she is so independent. I served her and her needy family for several months before she told me she would be my concubine. I disobeyed God by covenanting with her before I was sure she was genuinely saved in Jesus (2 Cor 6:14-7:3; Prov 5:20,21; 1 Kings 11). I thought her testimony to attending church and singing in the choir was enough at first, but then I discovered she had no real relationship with Jesus, no time in the Bible or prayer. She "left" me by telling me to not come around for a while, and I took that to be a 1 Cor 7:12,15 termination of marital relationship.
My fourth single mother of eight, AsianMexAm concubine by covenant, was abandoned by her husband and the father of 7 of her children. He left and married a woman from his church. She worked for me as my housekeeper once a week for several months and I got involved with her family. I disobeyed God by covenanting with her before I was sure she was genuinely saved in Jesus (2 Cor 6:14-7:3; Prov 5:20,21; 1 Kings 11). I thought her testimony of believing Jesus was God and Savior, and not Michael the archangel as most JW's believe, was enough but when the ladies at the churches I took her to rejected her rudely and unkindly, she gave up broken hearted and went back to being a nominal JW out of honor to her mother. She scaled down our relationship to good friends after her pastor persuaded her that polygyny was an OT thing and not for today.
An then there is the widow MexAm lady , a very godly church attending-building lady who reads her Bible twice a day and gets down on her knees to pray several times a day, who let me know that she needed to maritally covenant with me becoming her godly marital partner by covenant after I had been ministering to/visiting/serving her for several months.
So the neglected ministry fields of the Deut 25:5; James 1:21; 1 Tim 5:14 are white to harvest and ready to be reaped for one called to wash feet and serve others.
***Deut 25:5If brothers live together and one of them dies and has no son, his wife shall not be married to a stranger outside the family. Her husband's [single or married] brother shall go in to her and take her as his wife and perform the duty of a husband's brother to her.
***1 Cor 7:8 I say to the unmarried and to bereft [abandoned or widowed (5503)] women: It is good for them if they remain [unmarried] as I am. 9 But if they are not consistently abstaining from sinning sexually, they should marry, for it is better to marry than to burn with desire.
***James 1:27 Pure and undefiled religion before our God and Father is this: to look after [bereaved, parentless, orphaned] children(3737) and widows [lacking husbands](5503) in their distress and to keep oneself unstained by the world.
***1 Tim 5:14 Therefore, I want younger widows(5503) to marry, have children, manage their households, and give the adversary no opportunity to accuse us.
(5503) ch>ra, — khay’-rah; feminine of a presumed derivative apparently
from the base of (5490) (ca>sma) through the idea of deficiency;
a widow (as lacking a husband), literal or figurative: — widow.
