I remember singing the lyrics to Hillsong United’s “Oceans” in my middle school chapel, begging the Lord to “lead me where my trust is without borders” and “take me deeper than my feet could ever wander.”
“You call me out upon the waters / The great unknown where feet may fail / And there I find You in the mystery / In oceans deep my faith will stand,” I sang, probably acutely aware of the pleated uniform skirt hugging my waist in an unflattering manner.
I imagined this “great unknown” to mean some exotic mission field, perhaps an unreached people group on a desert island, where He would call me and I would bravely go.
There has since been controversy over Hillsong’s theology, and I’m in a faith tradition that doesn’t use that song for corporate worship. But young me meant those words with all her heart.
In college, deeply burdened by the stark racial divides in my American Deep South upbringing and university life, I prayed earnestly to “be a part of unity in diversity in the church.” I meant those words too, and years later, God answered me—in a far more literal way than I ever could have imagined.
In August of 2025, I married my husband David, an Afro-Latino Colombian I met on a mission trip in high school. We had no idea the Lord would weave our cross-cultural friendship into something more, but it’s been the adventure of a lifetime.
Our wedding was a transcendent celebration — guests of all colors and ethnicities praising, dancing, and singing side by side. Raindrops mixed with flower petals as we walked back down the aisle, and a breathtaking double rainbow graced our exit. It felt like a taste of heaven.
Before getting married, we carefully weighed the costs. We knew we would face challenges other couples wouldn’t. There is so much unknown in any relationship, but especially a cross-cultural relationship. There are millions of experiences that shaped his childhood that I will never understand. He grew up taking a cart to a water hole in the mornings, and I grew up in the suburbs.
There are values and understood norms that we stumble upon and learn only by crossing. Even though we speak each other’s languages, there are still references, jokes, and nuances that are hard to grasp. I’ve had people tell me they don’t think they could be in a cross-cultural relationship for all those reasons.
Visiting my husband’s rural coastal hometown is a perfect visual of these differences. The simple task of arrival is no simple task for me. On one recent occasion, I threw up three times in his backpack on a ten-hour overnight bus ride. Then, to get back, we had to cross the river in a handmade wooden boat that carries vehicles and people across through a pulley system. (Quite literally I was out upon the waters, praying the barge wouldn’t fail with a massive van, motorcycle, and us on it.)
But once we are there, it’s always worth it. His church friends have embraced me as their own. His mom delights in serving us the most wonderful home-cooked Caribbean food. We walk fifteen minutes from his house in our chanclas to the coast, and we are often greeted with the most stunning, fuchsia-infused sunsets spread across the entire horizon, throwing vivid oranges and pinks onto the waters below.
Normally, the vastness of the ocean and the mystery of its depths feel frightening to me. But on one of these occasions, as we stood hand-in-hand gazing at the sky, I was struck with a thought: the unknown can be beautiful. The vast mystery ahead of me was breathtaking, stunning in its splendor.
I realized that was my life, our marriage. God had called me into a great unknown where my feet could easily fail, but in His mercy, it was far more beautiful than I ever could have imagined. And as the song says, His grace abounds in deepest waters, and His sovereign hand will be my guide — every step of the way.
David and I have our differences. There are things we work through that other couples don’t. Sometimes it’s frustrating. Sometimes there are tears. Overabundant communication is a must. We’ve already faced challenges, and I’m sure there will be many more.
But his infectious exuberance, his perceptive wisdom, his unwavering support of my dreams, the energetic dancing he sweeps me up in, his huge smile, his kind eyes, his soft heart, make it all so very worth it. Despite our drastic disparities in upbringing, ethnicity, and culture, I have always felt known, seen, and safe with him. In fact, I feel that our similarities far outweigh our differences. Because above all, our primary culture is one we do indeed share — our faith.
I work in university ministry in Colombia, and when students find out I’m a gringa married to a costeño, their curiosity has no bounds, paving a path for me to share about the covenantal love of Christ towards His church. Hearts open to me in ways they never would have if I weren’t married to someone from their culture. And if or when we do move to my hometown, I pray our relationship will be a quiet statement of hope for racial unity amidst so much division.
My message is this: The unknown can be scary, and you do need to carefully consider the risks of walking out upon the waters. But don’t let that prevent you from seeing how breathtakingly beautiful it is.
His sovereign hand will be your guide.
