The first and best argument for early marriage — providing, of course, that one meets a good person and believes this person will also be a good parent and/or provider — is that it forces you to grow up.
Nothing — and I mean nothing — makes us grow up as much as marriage does. Children are a close second, but the maturity leap from singlehood to marriage is still greater than the maturity leap from marriage without children to marriage with children.
The problem today is that becoming mature is not even on the list of most young people’s life goals. If anything, staying immature — committing to no one and remaining dependent on others — is more of a goal.
That is what “not ready” usually means.
Putting aside the financial issue, which we will address, “not ready” almost always means not willing — not “not ready” — to take on the permanent commitment to someone else that marriage entails.
Why were people throughout history ready to commit to marriage at a much younger age than people today? Only because society expected them to become adults at a younger age than today. Nothing makes you an adult as much as responsibility does. And no responsibility makes you an adult as much as marital responsibility.
And why, even today, are religious Jewish and Christian young men and women ready to marry in their early 20s? Because their values and their culture expect them to.
Let’s be honest. “I’m not ready” is usually a statement of emotional immaturity even when the person is otherwise a wonderful and responsible man or woman.
