Sixty years ago, Mathinya and Matsepiso Sesioana made promises about a future they had not yet lived. They could not have known every joy that awaited them, nor every disagreement, sacrifice and difficult season. Six decades later they are still together, and still choosing one another.

Asked what has kept their marriage intact for 60 years, their answer is strikingly uncomplicated. “Fear God and love each other.”

That sentence carries the theology on which they built their home. For the Sesioanas, marriage has never been merely a social arrangement between two people.

A covenant, not an arrangement

The biblical vision of marriage begins with God. Genesis 2:24 establishes it within creation itself: a man leaves his father and mother, is joined to his wife, and the two become one flesh. Jesus affirmed the union in Matthew 19:6, declaring that what God has joined together, no one should separate. Marriage is sacred not because two perfect people enter it, but because two imperfect people invite a perfect God into their covenant.

The Sesioanas are refreshingly realistic about that imperfection. “As sinners, we accept that challenges and difficulties are inevitable in married life.”

Their testimony challenges the assumption that a successful marriage is one without problems. Strong marriages are not those that avoid difficulty; they are those that learn to face difficulty without letting it destroy the covenant.

From theory to action

Their most striking reflection comes when they are asked what the words “I love you” mean after 60 years.

“Then, it was theory, but now it is actions; not words and names, features, but experience.”

There is theology in that. Biblical love is demonstrated rather than declared; 1 John 3:18 urges believers to love not in word or tongue, but in deed and truth. Young love begins with attraction and words. Mature love acquires calloused hands. It works, sacrifices, forgives, stays present, and learns the other person again as both change through the seasons of life.

The Sesioanas describe love as “reciprocal in all aspects.” Neither spouse is only a recipient of the other’s affection; both contribute to the health of the marriage.

Asked what they still appreciate about one another after six decades, they say: “we still care and love each other just as, or even more than, when we married.” Love need not diminish with familiarity. Properly tended, it can deepen.

Forgiveness as principle

Sixty years together provides ample opportunity to discover one another’s weaknesses. Forgiveness has therefore become foundational.

“To us forgiveness is a principle, not a choice. ‘I was wrong’ is a key to reconciliation.”

Those three words can be harder to say than I love you. A marriage cannot flourish where pride keeps winning. For the Sesioanas, forgiveness is not an emergency measure held back for major crises but part of the ordinary maintenance of love.

Their spiritual practice reinforces it. “Having made Christ our Lord, we always resolve our differences before we pray.”

Prayer, in their marriage, is not used to cover unresolved conflict. You cannot kneel together before God while refusing to humble yourself before the person kneeling beside you.

The ordinary habits

A 60-year marriage does not survive on a ceremony that happened six decades ago. The Sesioanas name the habits that have preserved their connection: “Kissing before leaving and when meeting, caressing, working and praying together, going out for holidays at least once a year.”

None of this is spectacular, and that is the point. Couples can share a house, children, bills and responsibilities while slowly ceasing to share themselves. Familiarity can quietly become neglect.

Counsel for the young

Their advice is notably practical, and pointed at a culture that can celebrate the wedding while underestimating the marriage.

“They take marriage as a honeymoon for life. Marriage has responsibilities like working, building a home, providing food and clothes and raising up children.”

There are bills after the wedding photographs, and decisions after the honeymoon. Love does not become less beautiful because responsibility enters; responsibility is one of the places where love proves itself.

What would they tell the young couple standing at that altar 60 years ago? “Work as a team, complement each other, don’t compete with each other, budget together and, above all, pray together.”

Complement, don’t compete. Marriage was never meant to be a contest over who earns more, achieves more, sacrifices more or speaks last.

What longevity does and does not prove

Celebrating a diamond anniversary should not romanticise the genuine pain that exists in some marriages, nor suggest that longevity alone proves a relationship is healthy. Marriage must always honour the dignity, safety and wellbeing of both spouses.

But when a husband and wife can look back after six decades and still describe one another as caring and loving, there is something worth both celebrating and learning from. The wedding establishes the covenant; the years cultivate it.

A strong marriage is not built by one extraordinary moment of saying “I do.” It is built by thousands of ordinary moments in which a husband and wife say, through their actions, “I still do.”
