Heart of Worship

Days of worship

Don Potter has been a close friend and regular guest speaker at the Scheife for over 20 years. Don has shaped generations of younger worship leaders: Jonathan and Melissa Helser, the McMillans, and many more who went through Don's school.

It is a great privilege for us to be able to offer you a time together with him. If you don't know Don, you must  experience his way and ability to invent spiritual songs spontaneously. And those who already know Don can look forward to this opportunity to be inspired by him again.

You are all cordially invited!

Warmly, Marcus & Rebecca Watta

Don and Christine Potter have been longstanding friends of ours and spiritual parents for many worshipers, intercessors, artists and musicians far beyond the United States. Their way of seeking and following God's Spirit in all things is impressive and inspiring. They will visit us n an exciting phase of their lives, in which Don devotes his mornings entirely to worship (he has done this before and this is where the book "Facing the Wall" came from) and Christine is redesigning her prayer mountain. They are passionate about sharing their wealth of experiences, how the presence of God can be cultivated in our lives, how nature longs for and responds to our worship, and how Heaven likes to answer our prayers.

Lilo Keller founded the Stiftung Schleife with her husband Geri. She is a concert pianist and has been known for many years for her worship, books and conferences. It is Lilo's gift to lead people into their vocation. She is a passionate worshiper and speaker at events in various countries around the world.

Marcus and Rebecca Watta direct music, worship, publishing an art in the Schleife. Among other things, they are known for their songs, various music productions, publications and, of course, their concerts together.

Other contributors:

Elke Reichert, Andreas & Stephanie Keller, Markus Fuchs, Daniela Bär, Tabea Kämpf, Marc Ebermann many others.

Workshop with Don/Christine Potter «Balance between skill and the Spirit of Truth»

As a result, after waiting on God and just praising Him alone for the past 6 years, He has shown me the importance of balance between skill and Spirit, and worshipping in Spirit and Truth. This is the subject that I feel I need to teach on, and exhibit as well.
