The Bible doesn't specify that either marriage or singleness is better. Instead, it discusses the responsibilities of marriage so individuals can decide if they're suited for it. The Bible presents marriage as a gift from God (Proverbs 18:22). God created Eve as a lifetime companion for Adam (Genesis 2:18). At times, though, singleness is more suited for fulfilling God's purpose, as was the case with the prophet Jeremiah who never married (Jeremiah 16:2). In the New Testament, Jesus acknowledged that marriage isn't for everyone and that some may choose singleness for the sake of serving God more devoutly (Matthew 19:3-12). Paul reaffirms this in his letter to the Corinthians (1 Corinthians 7:7, 34). Marriage is not better than singleness, and singleness is not better than marriage. God's plan and purpose vary per each individual.
Do I or don't I? That question applies to whether to get a doughnut with your morning coffee to much weightier decisions like saying “I do.” Marriage isn't for everybody and everybody isn't for marriage. Isn't it interesting, though, that every person will experience singleness; not everyone will experience marriage.
So which is better than the other? The answer is neither. We can honor God whether we are married or single. In marriage, we have the opportunity to reflect Christ through sacrificially loving our spouse, being faithful, and living out our faith with our spouse (Ephesians 5:25–33). In singleness, we have the opportunity to devote ourselves to God and serve others without the responsibilities that come with marriage (1 Corinthians 7:32–35). Neither relationship status makes someone more complete, more mature, or more valuable. Our identity isn't “single,” “married,” “dating,” or “divorced”—it is found in Christ.
That can be difficult to remember in a culture that can make marriage seem like the finish line of adulthood—or singleness as the ultimate "do what you want" ideal. Marriage and singleness can both be good gifts; neither is a consolation prize. If you're single, don't put your life on hold waiting for a spouse; use this season to grow in your relationship with God, serve others, build meaningful friendships, and pursue the purposes He has given you. If you're married, don't expect your spouse to fulfill needs that only God can meet; instead, see your marriage as an opportunity to love sacrificially, grow in holiness, and point each other toward Christ. Above all, whether married or single, seek to honor God with the life He has given you (1 Corinthians 10:31).
