When two people stand before God, family, and friends to say “I do,” they are pledging their love and commitment with sincerity and joy. But what no couple fully understands in that sacred moment is the breadth of change that marriage will bring. We often imagine that life after the vows will look like an extended honeymoon—sweet, smooth, and filled with unending romance. The truth is, marriage is a journey of continual adjustment.
The Reality of Change in Marriage
Marriage doesn’t freeze life in place; it opens the door to seasons of change. Careers shift, families grow, bodies age, priorities evolve, and circumstances beyond our control reshape daily life. What felt simple in the dating season often becomes more complex when bills, responsibilities, or unexpected trials enter the picture.
“I didn’t know that when I said I do” is the quiet thought many couples have when faced with realities they didn’t anticipate:
-
The differences in how you handle stress.
-
The adjustments that come with children or waiting for them.
-
The sacrifices required for finances, family responsibilities, or even personal dreams.
-
The growth needed in communication when disagreements arise.
Why Adjustment Is Not Failure
It’s easy to see change as a sign that something has gone wrong. In reality, change is a natural part of life—and marriage is God’s training ground for learning how to adapt together. The vow of “for better or for worse” acknowledges this very truth: there will be seasons of stretching. Adjustment is not failure; it’s evidence of two people growing together rather than apart.
Paul reminds us in Philippians 4:12–13 of his ability to adapt to every circumstance through Christ’s strength. In the same way, couples are called to lean on God’s grace, learning to walk through change hand-in-hand instead of back-to-back.
Keys to Adjusting Well
-
Communicate Honestly – Don’t assume your spouse knows how you feel. Share your fears, hopes, and frustrations openly and lovingly.
-
Stay Flexible – Hold tightly to your commitment, but loosely to your preferences. Love sometimes requires compromise.
-
Grow Spiritually Together – Prayer, worship, and Scripture anchor your relationship when change feels overwhelming.
-
Celebrate Small Wins – Recognize and affirm each other for the little ways you’re learning and adjusting.
-
Seek Counsel When Needed – Sometimes change is hard to navigate alone. Godly mentors or professional counseling can provide perspective and encouragement.
The Beauty of the Journey
When you said “I do,” you may not have known all the twists and turns that life would bring, but God did. He designed marriage as a covenant where two people learn, grow, and become more like Christ through the process of adjusting to one another. Change doesn’t have to be a threat; it can be the very soil where your love matures.
So the next time you find yourself whispering, “I didn’t know that when I said I do,” remind yourself of this: you don’t have to know everything in advance. You only need to keep choosing each other, keep choosing growth, and keep choosing God—day after day.
