A Christian spinster is usually advised to patiently wait for a monogamous marriage before having children. "Single motherhood is stressful. A child needs both parents". Later on in life, she will be told to consider adoption if she is feeling lonely, rather than have her own child out of wedlock. If single motherhood is not ideal for her own child, does someone else's child deserve it? Is it even in the child's own interests?
1. The best adoptive home for an orphan is the one where the married couple already have a child or 2 of their own. The wife's health has been stabilized by childbearing. She is not dragged to the surgical theatre by fibroids for not having her own biological child (https://punchng.com/virginity-does-not-protect-from-fibroid-ivf-expert/). The couple are not shedding tears of frustration every time the wife menstruates, making the adopted child wonder, "Am I not good enough to make them happy?" The adopted child is not emotionally crushed by hearing them pray to get their own child. They are likelier to stay married for life than childless couples (who may break up to test their fertilities elsewhere). Very few people will know they are not the biological parents.
2. The 2nd-best adoptive home is the one with a childless couple. At least, they have each other. They can wait for the child to sleep at night before trying to have their own child. The child cannot interfere with their love life. Once the wife remains healthy, they will be able to do their best by the child.
3. The next-best home is the one with a single mother. Even if she doesn't ever have the chance to get married, she already has at least one biological child. She doesn't have to fear menopause any longer and is less prone to fibroids than a childless woman. She can afford to bear a "Mrs" title (with the same surname as the children) , in order to "dignify" the children.
4. The worst home is the one with a childless spinster. (a) She is highly prone to fibroids , which tend to regrow even after surgery until she gives birth biologically. (b) Adoption scares away most eligible men (who don't want to marry single mothers and carry another man's responsibilities) from her, while the biological single mothers (who are also fibroid-free) hide their children with relatives or orphanages in order to attract bachelors for marriage. (c) A spinster and her date will be disturbed by the adopted child during his evening visits, since they don't live together as a couple. (d) Since she has no husband by her side and is still a "Miss", she must explain to curious wives asking for the child's father that the child is adopted (and not born by her for anyone's husband) for the child's own safety.
[ Caring for someone else's child ] + [ the health problems of childlessness ] - [ the support of a husband ] = [ the worst of all worlds ].
Orphanages provide a vital service for abandoned children. They foster them till 18 years of age before sending them out , to make way for new babies. Other members of the society (including people who can't afford to adopt them) can donate the little money they have to the orphanage. Politicians and other bigwigs also do the same. "Little drops of water, little grains of sand, make the mighty ocean and the beauteous land". The absence of any extra help or inheritance after age 18 is compensated for by the absence of extended family responsibilities towards nephews, nieces, aged relatives, etc later in life. Agony aunts, the right books, etc will provide emotional support.

People should have only the number of children they can cater for, without depending on others to foster or adopt them. God is not against family planning. After having enough children ,how can a married couple obey Matthew 19:9 ("don't divorce your spouse except on the grounds of adultery") ; 1 Corinthians 7: 3-5 ("don't deprive each other of sex, except by mutual consent for a SHORT period of prayer") and 1 Timothy 5: 8 ("whoever doesn't provide for his own family is worse than an unbeliever") without using some form of family planning? It is abortion that God hates (Exodus 21: 22-25 ; Psalm 139: 16 ; Ecclesiastes 11: 5 ; Isaiah 49: 1 ; Luke 1: 41, 44 ), not pregnancy prevention. God killed Onan for preventing CHILDLESS Tamar from having any child after marrying her in order to get her late husband's (his late brother's) property (Genesis 38: 1-11 ; Deuteronomy 25: 5-10). God spared Ruth's closest male in-law, who was honest enough to decline both her and Mahlon's property and let richer Boaz marry her (Ruth 4: 1-10). Don't be a "dog in the manger".
