God did not create man to be alone. The Lord God said, “It is not good for the man to be alone. I will make a helper suitable for him.” Now the Lord God had formed out of the ground all the wild animals and all the birds in the sky. He brought them to the man to see what he would name them; and whatever the man called each living creature, that was its name. So the man gave names to all the livestock, the birds in the sky and all the wild animals. But for Adam no suitable helper was found. So the Lord God caused the man to fall into a deep sleep; and while he was sleeping, he took one of the man’s ribs and then closed up the place with flesh. Then the Lord God made a woman from the rib he had taken out of the man, and he brought her to the man. The man said, “This is now bone of my bones and flesh of my flesh; she shall be called ‘woman,’ for she was taken out of man.” That is why a man leaves his father and mother and is united to his wife, and they become one flesh." Genesis 2:18-24
Indeed it is not good for a man to be alone. For Pastors reading this passage, it is YOUR responsibility then to find an appropriate mate for the single men and women in your congregations, especially for those single men who want to be married. Pastors, again, feed your sheep. Look after your flock. Look after their needs --- Spiritual, Emotional and Physical, because most single Christian men, if they don't find what they need at your Church, will go elsewhere in search to fill that need. Sometimes, they will go to a different Church to fill that need, but sometimes they will not arrive at places wherein those folks should go to get their needs filled.
"...each man should have sexual relations with his own wife, and each woman with her own husband. The husband should fulfill his marital duty to his wife, and likewise the wife to her husband. The wife does not have authority over her own body but yields it to her husband. In the same way, the husband does not have authority over his own body but yields it to his wife. Do not deprive each other except perhaps by mutual consent and for a time, so that you may devote yourselves to prayer. Then come together again so that Satan will not tempt you because of your lack of self-control. I say this as a concession, not as a command. I wish that all of you were as I am. But each of you has your own gift from God; one has this gift, another has that. Now to the unmarried and the widows I say: It is good for them to stay unmarried, as I do. But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion. To the married I give this command (not I, but the Lord): A wife must not separate from her husband. But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife." 1 Corinthians 7:2-16
There is an exception for those whose spouses are not Christians:
"To the rest I say this (I, not the Lord): If any brother has a wife who is not a believer and she is willing to live with him, he must not divorce her. And if a woman has a husband who is not a believer and he is willing to live with her, she must not divorce him. For the unbelieving husband has been sanctified through his wife, and the unbelieving wife has been sanctified through her believing husband. Otherwise your children would be unclean, but as it is, they are holy.
There is an exception for those whose unbelieving spouses abandon them:
But if the unbeliever leaves, let it be so. The brother or the sister is not bound in such circumstances; God has called us to live in peace. How do you know, wife, whether you will save your husband? Or, how do you know, husband, whether you will save your wife?" 1 Corinthians 7:1-16
Pastors, this is your responsibility. Do what is right by your flock. Pay attention to the singles in your congregation. Your Church is not only about the married people in it. It is also about the single folks. It is also about finding a Proverbs 31 wife for your single men:
A wife of noble character who can find?
She is worth far more than rubies.
Her husband has full confidence in her
and lacks nothing of value.
She brings him good, not harm,
all the days of her life.
She selects wool and flax
and works with eager hands.
She is like the merchant ships,
bringing her food from afar.
She gets up while it is still night;
she provides food for her family
and portions for her female servants.
She considers a field and buys it;
out of her earnings she plants a vineyard.
She sets about her work vigorously;
her arms are strong for her tasks.
She sees that her trading is profitable,
and her lamp does not go out at night.
In her hand she holds the distaff
and grasps the spindle with her fingers.
She opens her arms to the poor
and extends her hands to the needy.
When it snows, she has no fear for her household;
for all of them are clothed in scarlet.
She makes coverings for her bed;
she is clothed in fine linen and purple.
Her husband is respected at the city gate,
where he takes his seat among the elders of the land.
She makes linen garments and sells them,
and supplies the merchants with sashes.
She is clothed with strength and dignity;
she can laugh at the days to come.
She speaks with wisdom,
and faithful instruction is on her tongue.
She watches over the affairs of her household
and does not eat the bread of idleness.
Her children arise and call her blessed;
her husband also, and he praises her:
“Many women do noble things,
but you surpass them all.”
Charm is deceptive, and beauty is fleeting;
but a woman who fears the Lord is to be praised.
Honor her for all that her hands have done,
and let her works bring her praise at the city gate.
