About Us
Calling Ministry is an international Christian ministry with a special heart for Africa. Our passion is to reach people with the Gospel of Jesus Christ, strengthen believers in their faith, and demonstrate God’s love through practical service.
Everything we do can be summarized in three core values:
Reach
We are committed to reaching people with the good news of Jesus Christ, with a particular focus on Africa.
We believe that every nation, tribe, and language is precious to God. That’s why we support evangelism, church planting, and missionary initiatives, giving people the opportunity to encounter Jesus and begin a personal relationship with Him.
Whether in cities or remote communities, our desire is to reach those who have not yet heard the Gospel and introduce them to the hope found in Christ.
Teach
Jesus not only called His followers to reach people, but also to make disciples.
For this reason, we invest in equipping believers, leaders, and churches. Through biblical teaching, training, mentoring, and practical support, we help people grow in their faith, discover their calling, and use their God-given gifts.
Our goal is to strengthen Christians, develop leaders, and help churches grow in a healthy way so they can effectively reach others.
Serve
God’s love is meant to be experienced, not just heard about.
That is why we serve wherever there is a need. Through education, practical assistance, care, and community projects, we seek to demonstrate the love of Christ and serve people in a holistic way.
We believe that the Gospel and practical compassion belong together. By serving others, we follow the example of Jesus and make God’s heart visible through our actions.
Our Mission
We are committed to reaching people, equipping believers, and strengthening churches so they can make a lasting impact in their communities.
Together with our partners and supporters, we work to share God’s love and help people grow as disciples of Jesus Christ.
Reach. Teach. Serve.
