CrossWalk – who are we?

CrossWalk, a ministry located in the Rhine-Main area, focuses on training and equipping Christians to become bold and powerful followers of Jesus.

By now, our team has grown to 13 precious men and women, most being graduates of our discipleship and leadership training programs. Together, we build God’s kingdom – through CrossWalk as well as the different spheres of influence each of us has, for example the churches that we attend.

Our EXTENDED CORE TEAM provides additional support in the leadership and development of the ministry.

Team Maren

Maren Batz

From 2016 to 2018, I attended the CrossWalk discipleship and leadership training, which greatly enriched and strengthened my spiritual life. The concept of the Bible school that doesn’t require full-time enrollment excited me from the beginning on, and even more so the open and appreciative interaction with each other. I would like to pass on what I learned and experienced at CrossWalk, and at the same time I am looking forward to continuing to learn and grow further while on staff.

Team Andreas Caren

Andreas & Caren Böttcher

During our CrossWalk Bible School time we had the privilege to intimately get to know the loving and gracious Father heart of God and the work of the Holy Spirit in a new way. Through all this, a completely new view of God and our identity in Christ has been a revelation to us.
We experienced the training as very enriching, and done in a manner where God’s Word was communicated in a loving and appreciative way. We look forward to coaching people who want to grow further in their personal relationship with God.

Team Melany

Melany Ehrig

It excites me to see people discover the God-given gifts He has placed inside of them and take hold of their callings by putting it all in practice in their own environment such as family, work place and that way extend His kingdom and in His authority wherever they are.
To encourage is a key for me in this.
Prayer is a joy for me, especially praying the Word of God which I experience as very powerful.

Team Conny

Conny Hornburg

Since joining Crosswalk in 2018, it has been consistently amazing for me to see how the powerful Word of God taught at CrossWalk-Training has changed the lives of individual participants.
Healing, deliverance, and divine purpose are topics near and dear to my heart.

The CORE TEAM has four members: Antje Janzen, Sebastian & Sabine Köhler and Kaisa Koistinen, who founded the ministry in March 2014.


Antje Janzen

After several years of working as a nurse and being involved in my church in Ruhr area, I attended a YWAM discipleship training school in 1997 and then went to Bible School at Glaubenszentrum Bad Gandersheim, where I after my graduation stayed for several years as a co-worker. In addition to administration and various leadership tasks, I was mainly involved in teaching, worship and counseling. Since the summer of 2012, I’ve lived in the Rhine-Main area. My passion is to preach the Word of God and help people to get into a passionate and childlike relationship with God. I want to challenge people to live a simple but powerful Christian life under the leading of the Holy Spirit and thus expand the kingdom of God.
To that end, in addition to my ministry here at CrossWalk, I am also out preaching in churches and ministries:


Sebastian & Sabine Köhler

We were born in Erfurt, Thuringia where we lived with our three children until we began our Bible school training in Glaubenszentrum, Bad Gandersheim. In Erfurt, we were active for many years in a local Evangelical Free Church, where we were involved with leading the worship teams, coordinating the “Wächterruf” (“Call of the Watchmen”) prayer initiative, doing children’s ministry and home group work. Missions trips to Mongolia, Guatemala, Kazakhstan and to the Native Americans have impacted and formed our lives very much. Our passion is to help people find their God-given destiny and come to the understanding of the riches God has given them in Jesus, and then help them to take concrete steps into the direction He has for them.


Kaisa Koistinen

I was born in Finland, where I also grew up and went to school. My life began to change radically when I in 1998 decided to follow Jesus and give up my old life. Already two years later I was on the mission field in China where I worked for four years, first in an orphanage and later among the underground church. After that I had the privilege of working with various leaders and ministries, including Randy Clark (Global Awakening) and Glaubenszentrum, Bad Gandersheim. I have resided in Germany since 2006 and live now in Frankfurt am Main. Over the years, I have had the opportunity to serve God in many different nations. My passion is to see a worldwide revival and to see nations are saved. I have an evangelistic heart, especially for the poor, forgotten and broken. My heart beat is to carry the Gospel to the darkest corners of this world. I love to minister prophetically and teach the Word of God.

Our spiritual roots

Of course we all have our own personal story of how we got saved and where he grew up spiritually.

Nevertheless, there is a certain “DNA” that all of us as in the CrossWalk core team carry, and which we value and embrace as our heritage. All of us have spent time in Glaubenszentrum e.V. in Bad Gandersheim, which naturally has greatly impacted our lives. We all did a bible school training there and some of us also worked there long-term as staff. Much of what you can read under „Why CrossWalk“ has its roots in that very significant time we spent there shaping us into who we are.

In addition to these common roots, we also see ourselves connected with the heritage of the healing and revival movement of the 1950s and 60s, where also the “Mother Bible School” of Glaubenszentrum in Dallas/Texas has its spiritual roots. (Christ for the Nations Int., CFNI).

As a ministry we have placed ourselves under the apostolic covering of Peter Wenz and furthermore belong to the D-Netz.
