The story behind Worldchanger

As children who grew up in the former GDR, Andreas and Tanja Walther had no connection to God. While searching for the meaning of life during their college years, they came to know Jesus Christ. Touched by God’s love, their world was fundamentally transformed. From that point on, they were passionate about inviting others to join them on this adventure with God.

In addition to their professional careers as a doctor and a teacher, they were actively involved for many years in a Christian youth club in Chemnitz. There, their hearts went out especially to teenagers and young adults in need. Their home often served as a shelter. For example, they took in a young woman who had been a drug addict and had just been released from prison for several months. Through the love and care of both of them, she came to faith in God. Today, this woman is married, has five wonderful children, and is in love with Jesus.

Christopher and the Founding
of the WorldChanger Mission Organization

Tanja and Andreas embody the triad of mission, discipleship, and mercy in a special way. They want to bring God’s love to people in a practical and straightforward way.

In 2015, they traveled to Tanzania for the first time to volunteer at a medical center. That experience completely changed their lives. It would mark the birth of WeltBeweger.

On the first day of their mission, a young Tanzanian named Sharifu Abdala Tifu came to the medical center. Their first encounter was already very special, and when he started calling them “Mom” and “Dad” after three days, the ice was broken. He then came to see them every day during their clinic hours, even though his toothache had long since gone away. He longed for fellowship, love, and acceptance.

A few days before their departure, he asked them why they loved him so much.

They told him that Jesus loves him even more and that they were simply passing on Jesus’ love.

That really shocked him at first. After all, he had grown up as a Muslim in a very strict family.

On the last day of their stay in Tanzania, Sharifu said to Tanja and Andreas: “I want this Jesus you have, too. What do I have to do?”
It was an unexpected and special moment. But after praying to give their lives to Jesus, everyone was overcome with a feeling of joy and freedom.

Sharifu was warmly welcomed into a nearby, vibrant community. There, he was given a new name: Christopher. Later, he was baptized in the presence of Andreas and Tanja.

His mother and his Muslim relatives had disowned Christopher. From then on, Andreas and Tanja were his father and mother.

A few weeks later, Christopher took in the first street children in his rented room in Mugumu… and kept saying “There is still no home here for these beloved children of God."

THIS ALSO TOUCHED THE HEARTS OF ANDREAS AND TANJA.

They were deeply moved; they couldn’t stop thinking about Christopher, Mugumu, and the lost children. Could it be that behind this encounter lay a call from God to Africa?

And just like that, God’s call was there! Impossible to ignore!

For there are many “Christophers” in Tanzania and all over the world. God also wants to touch the other lost, suffering, poor, and sick people and transform their world into a life of victory.

The vision of WeltBeweger / WorldChanger was born.

The mission organization was founded in Chemnitz in early 2016.

Andreas and Tanja sense that this call from God is their life’s work. They are ready to walk this long journey with their friends and colleagues. At the same time, they realize that this will require many people who wholeheartedly follow the calling to be WeltBeweger.

Out Vision

Our vision is that God’s love will transform individuals, cities, and nations, and that through this, the Kingdom of God will spread throughout society.

WorldChanger operates on the basis of the
Apostles’ Creed of the Evangelical Alliance.

I believe in God the Father Almighty,
the Creator of heaven and earth.
And in Jesus Christ, His only Son, our Lord,
conceived by the Holy Spirit,
born of the Virgin Mary,
suffered under Pontius Pilate,
crucified, died, and was buried,
descended into hell,
rose again from the dead on the third day, ascended into heaven;
He is seated at the right hand of God, the almighty Father;
from there He will come to judge the living and the dead.
I believe in the Holy Spirit,
the holy Christian Church,
the communion of saints,
the forgiveness of sins,
the resurrection of the dead,
and eternal life.
Amen
