Sara Diaz Kamińska

A woman with a gentle heart and strong faith. Deeply in love with God and rooted in His Word, she heard the Lord’s call in 2017, deciding to leave her life in Quito, Ecuador’s capital, and move to Poland to serve God and people there. Her greatest desire is to see people grow spiritually, experience inward transformation, and develop an ever-increasing hunger for God’s presence.

About God she says: “I love His Father’s heart. He is so madly in love with us! He never gives up—He is always fighting for us. Every day He looks for a way to show His children how much He loves them. When He corrects, He does so in love. He forgives. He transforms. He takes our greatest pain and turns it into joy. That is who my God is!”

She is the perfect support and complement to her husband. Family is an incredible gift from God to her, and she has a true passion for traveling and showing the world to her son David and daughter Abigail.

TESTIMONY

I was born in Quito, the capital city of Ecuador. I grew up in a Christian family—my parents are pastors of the “Su Presencia” Church, which has locations throughout our country.

During my early years, I lived in two different worlds. One was the Church, and the other was the “everyday life of school.” I realized that my friends viewed Christians as boring and religious people, so I didn’t want them to identify me as one.

One evening, as I was reading the Bible in my room before going to sleep, its words suddenly began to touch my heart, and the Holy Spirit came into my room in such a powerful way that every word I read came alive. My shame turned into courage when the Holy Spirit began speaking to me, teaching me, and correcting me. Suddenly, God was no longer just my parents’ God. He became my God and my Savior.

The next day, after being filled with the Holy Spirit, I was ready to start sharing the Gospel with my friends. I did this at school, in homes, in parks, and on the streets. At the age of 12, I started my first home group, which had ten teenagers. That’s how my ministry was born.

I graduated from the Business School in Ecuador with a major in marketing, and I also completed a course in radio and TV production at the Centro Cristiano de Comunicaciones. During my fourth year of studies, I went to the United States, where I earned a Bachelor’s degree in Electronic Media from Northwestern University. At the same time, I minored in Bible studies and took several courses to prepare for ministry.

After returning to Ecuador, I began working at a well-known production house while actively serving in the church. I strongly felt God’s calling, so I decided to leave my professional career and devote myself fully to serving Him. I served as a worship leader and ministered at many youth conferences across the country. I also founded a worship school called “Aviva” in Quito.

In February 2017, I married Jakub, with whom I share the same calling, mission, and ministry—ideas birthed by the Holy Spirit Himself. We live in Warsaw, where we pastor NOF Church, a local ministry of the Nations On Fire Foundation, while also serving actively throughout Poland and beyond its borders.

NATIONS ON FIRE

Jakub & Sara Kamińscy

We believe that God has brought us together to fulfill His will, which is why we have chosen to devote our lives to serving God and proclaiming the Gospel of Jesus Christ.

Our personal dream is for every person’s heart to catch fire for Jesus and for each one to discover the calling God has placed upon their life. Together, we want to expand the borders of God’s Kingdom and witness the greatest revival in the history of our nation.

We are convinced that when God pours out His glory on our country, Poland will become the epicenter of a revival that will reach many nations. We dream of God’s presence being so tangible that we will experience numerous signs and wonders, just as the Lord has promised.

Jakub Kamiński

Pastor, evangelist, visionary, radical Christian, passionately in love with God. In 2015, while still a professional soccer player, he had a real encounter with the living God—one that turned his life upside down and ignited an extraordinary passion for Jesus. He left his sports career behind to further the cause of God’s Kingdom, founding the Nations On Fire ministry together with his wife, Sara. This ministry has led to the salvation of hundreds, if not thousands, of souls and has reached six continents. In obedience to the Holy Spirit’s leading, he travels far and wide, sharing the Gospel and awakening people’s passion for God.

His greatest desire is to see people who are hungry for God’s presence, people who not only meet their Lord on Sundays at church but also live with Him every minute of their lives.

Today, he is the pastor of NOF Church in Warsaw, a happy husband to Sara, and the father of David and Abigail.

TESTIMONY

I was born into a Christian family, where from my earliest years my parents introduced me to God and instilled in me a passion for Jesus. But to truly know His supernatural power, I had to walk through some dark valleys.

At age 12, my athletic potential was discovered. I left home for the youth soccer academy of one of the country’s best clubs, where my talent began to explode. At 16, I was called up to the Polish national youth team. I then moved to another club and signed a professional contract. From that point on, parties, alcohol, gambling, and various substances became my everyday reality.

During a match when I was 23, I suffered a knee injury and underwent a complicated surgery. I returned to the game, but in another match, the injury recurred, and I ended up on crutches. The doctors gave me no hope—they said I would struggle with the aftermath of that injury for the rest of my life.

A few weeks later, I found myself at a Christian conference to which my parents had invited me. During the event, God’s presence came down in such a tangible way that I was deeply moved by His love and surrendered my life to Jesus. At that very moment, I was also completely healed. Filled with indescribable joy, I ran out of the meeting and leapt around the park, rejoicing in the reality of God’s miracle-working power.

After that experience, nothing could stop me! I began seeking a relationship with God persistently and found in Him what no one and nothing in this world could offer—love, freedom, joy, and happiness. I started sharing the message of Jesus everywhere I went: on the streets, in stores, even in banks.

At the end of 2015, I embarked on my first trip as an evangelist, attending a conference in South America where I preached the Word and prayed for people. This experience completely captivated me and still does to this day! Since then, together with my wife, Sara, I have been proclaiming a Gospel inspired by the power of the Holy Spirit, teaching the Word of God, and equipping believers for ministry all around the world.

My personal dream is for every person’s heart to burn for Jesus and for the Gospel to spread among those who do not yet know Him.
