Divorce, Widows, and being single are all addressed here. There is some carry over from chapter 6 on the body and in marriage how we belong to each other but Paul goes further into how marriage and singleness can impact faith and focus. Faithful spouses can carry each other (7:12-16) but we can also lift up being single in fact as a better way. Churches invest a lot of time resourcing families but struggle at times to connect with singles because even then it tends to drive toward marriage (singles groups etc.). It's a great time to explore the spiritual side of marriage, singleness, and widowhood.
1 Corinthians 7:32-38
I want you to be free from anxieties. The unmarried man is anxious about the things of the Lord, how to please the Lord. But the married man is anxious about worldly things, how to please his wife, and his interests are divided. And the unmarried or betrothed woman is anxious about the things of the Lord, how to be holy in body and spirit. But the married woman is anxious about worldly things, how to please her husband. I say this for your own benefit, not to lay any restraint upon you, but to promote good order and to secure your undivided devotion to the Lord.
If anyone thinks that he is not behaving properly toward his betrothed, if his passions are strong, and it has to be, let him do as he wishes: let them marry—it is no sin. But whoever is firmly established in his heart, being under no necessity but having his desire under control, and has determined this in his heart, to keep her as his betrothed, he will do well. So then he who marries his betrothed does well, and he who refrains from marriage will do even better.
And Pharisees came up to him and tested him by asking, “Is it lawful to divorce one's wife for any cause?” He answered, “Have you not read that he who created them from the beginning made them male and female, and said, ‘Therefore a man shall leave his father and his mother and hold fast to his wife, and the two shall become one flesh’? So they are no longer two but one flesh. What therefore God has joined together, let not man separate.” They said to him, “Why then did Moses command one to give a certificate of divorce and to send her away?” He said to them, “Because of your hardness of heart Moses allowed you to divorce your wives, but from the beginning it was not so. And I say to you: whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.”
The disciples said to him, “If such is the case of a man with his wife, it is better not to marry.” But he said to them, “Not everyone can receive this saying, but only those to whom it is given. For there are eunuchs who have been so from birth, and there are eunuchs who have been made eunuchs by men, and there are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven. Let the one who is able to receive this receive it.”
