Every ministry has a story. Behind every church, every pulpit, and every congregation is a person who said yes to a calling that was bigger than themselves.

The ministry journey of Dr. Derek Achenbach — Derek Randall Achenbach — is one of those stories.

It is a story of a man who encountered the living God through His Word, was gripped by a conviction that the Church had drifted from its Biblical foundation, and responded by building something different: a church where the Bible is the authority, denominational labels are set aside, and believers are equipped to walk in their true identity in Christ.

A Calling Rooted in Scripture

Dr. Achenbach's ministry was not born out of ambition or a desire for platform. It was born out of a deep encounter with the Word of God.

Like many who are called to pastoral ministry, Dr. Achenbach found that the more he studied Scripture, the more he was burdened by the gap between what the Bible describes as the Church and what he observed in much of contemporary Christianity.

The Church Jesus prayed for in John 17 was unified. The Church the Apostle Paul described in Ephesians was built on the foundation of Christ alone. The Church in Acts was marked by the power of the Holy Spirit, the breaking of bread, prayer, and the apostles' teaching.

What Dr. Achenbach observed in much of modern Christianity was something different: fragmented, divided by denominational labels, often more shaped by tradition and preference than by Scripture.

This burden became a calling.

The Conviction That Shaped His Ministry

One conviction has defined Dr. Derek Achenbach's ministry more than any other:

Denominational labels inhibit the Body of Christ.

This is not a peripheral concern for Dr. Achenbach. It is central to his understanding of the Gospel and the Church.

When believers identify primarily as Baptists, Methodists, Presbyterians, Charismatics, or any other denominational label, they are — often without realizing it — placing a man-made identity above the identity God has given them in Christ.

The result is division, competition, and a weakened witness to the world.

Jesus prayed:

"That they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me." — John 17:21

Dr. Achenbach has spent his ministry calling believers back to this prayer — back to the unity that is only possible when Christ, not denomination, is the center.

Founding God's House Ministries

This conviction led Dr. Derek Achenbach to found God's House Ministries in Phoenix, Arizona.

God's House Ministries was established as a non-denominational adult Christian church — a place where believers could gather around the Word of God, worship in spirit and truth, and grow in genuine community without the barriers of denominational identity.

The name itself is significant. It is not named after a denomination, a theological tradition, or a founder. It is named after what it is meant to be: God's house.

"For my house shall be called a house of prayer for all peoples." — Isaiah 56:7

From its founding, God's House Ministries has been committed to:

• Expository Bible teaching — working through Scripture systematically
• Non-denominational identity — Christ alone as the foundation
• Adult discipleship — equipping believers for spiritual maturity
• Authentic community — genuine relationships built on shared faith
• Prayer — a culture of dependence on God

Sunday Gatherings in Phoenix, AZ

God's House Ministries holds Sunday services at 9 AM and 11 AM in Phoenix, Arizona.

These gatherings are designed for adults who are serious about their faith — believers who want more than a Sunday morning experience and are committed to growing in their knowledge of Scripture and their walk with Christ.

The services are marked by:

• Worship that is God-centered and Scripture-saturated
• Expository preaching from Dr. Derek Achenbach
• Prayer — both corporate and personal
• Community — genuine connection with other believers

The Book That Defines His Message

In addition to his pastoral ministry, Dr. Derek Achenbach is the author of:

The Inhibiting Denominational Label of Man

This book is the written expression of the conviction that has shaped his entire ministry.

In it, Dr. Achenbach examines the history of denominationalism, the Biblical case for Christian unity, and the practical steps believers can take to move beyond the labels that divide them and embrace their true identity in Christ.

The book is available on Amazon in Paperback, Hardcover, and Kindle formats, and on Dr. Achenbach's Amazon Author Page at amazon.com/author/dr.achenbach.

A Ministry That Continues to Grow

The ministry journey of Dr. Derek Achenbach is not a story that has reached its conclusion. It is a story that is still being written.

God's House Ministries continues to grow as believers in the Phoenix area discover a church where the Bible is taught faithfully, denominational barriers are set aside, and every person is welcomed as a fellow member of the Body of Christ.

The blog, the book, the Sunday gatherings, the prayer ministry — all of it is an expression of one man's response to a calling he received from God: to help the Church become what Jesus prayed it would be.

"I have come that they may have life, and that they may have it more abundantly." — John 10:10

That is the ministry of Dr. Derek Achenbach. That is the mission of God's House Ministries.
