This comes up regularly in discussions about being single (of which I am an expert by now), and here is my attempt to answer the question.
- Remember that God is sovereign. You're not single by mistake; you're single because this is the best for you at this time. This is for your good and His glory.
- Think about why you are discontent and deal with the underlying issue.
- Is the problem not trusting God's sovereignty?
- I suggest reading Trusting God by Jerry Bridges with a trusted friend who will help you figure things out.
- Do you believe that God is holding out on you?
- Again: Trusting God.
- Have you been lied to about the role of women? Have you been told that marriage is God's highest calling for women? Or that marriage is better than singleness? Or that you are somehow less of a godly woman for being single? (I know that people may not have said all this, but they often say enough that seems to mean all this.)
- First, read 1 Corinthians 7.
- Then, listen to Pastor James preaching about this: https://gracelife.ca/sermon_book/1-corinthians/page/7/
- Start with May 21st, skip June 4th, listen to June 11th, 18th, and September 10th.
- Live your life. Don't put it on hold because you're waiting for marriage (or anything, really). This is the life God has given you, so live it. And enjoy it! Serve the church. Get a job. Go to school. Invest in the lives of the people around you. Practice hospitality. Be who God has called you to be right now.
- Finally, don't believe anyone who says "You just need to be content in your singleness and then God will send you a husband." This is nonsense and obviously untrue (note the number of discontented people who are married and the number of contented people who are single). You're not being content to manipulate God into sending you a husband; you're being content to obey God's commands to trust Him and to submit to His sovereignty in your life.
