Helping Churches Share The Gospel Message

Helping Churches Share The Gospel Message

Pastors of normal-sized churches want to see their people sharing the gospel again. They long for real evangelistic momentum, not simply activity on a calendar.

But over time, evangelistic urgency can begin to fade. Invitations become rare. Conversations about Jesus happen less often. Churches that once experienced gospel momentum can begin to feel stuck.

IRPG Mission comes alongside pastors through revival meetings, pulpit supply, and evangelistic training that encourage a culture of evangelism in the local church.

Our focus is simple.
  • Strengthen the pastor
  • Equip the congregation
  • Keep the gospel central

The Calling Behind IRPG Mission

The Calling Behind IRPG Mission

In 2015, while working in Nelson County, Virginia, Derek Keiser began praying about a growing sense that God was leading him into a mission field.

What began as a burden to minister to wildland firefighters soon became a calling to proclaim the gospel and encourage those serving on the fireline.

That ministry continues today whenever opportunities arise to share Christ and encourage those working in the wildfire community.

Over time, God expanded that calling beyond the fireline and opened doors to serve churches through evangelistic ministry.

Today, IRPG Mission serves churches through revival meetings, pulpit supply, and evangelistic training that strengthen pastors and equip congregations to share the gospel with renewed urgency and boldness.

What “IRPG” Means

Incident Response Pocket Guide  a field guide used by wildland firefighters.

Firefighters rely on the IRPG as a trusted reference for safety, direction, and standard practices while working on the fireline.

In a similar way, IRPG Mission exists to point people to the ultimate guide for life and faith — the Word of God.

The phrase “I’m Ready to Preach the Gospel” reflects both the name and the mission of the ministry.IRPG stands for Incident Response Pocket Guide, a field guide used by wildland firefighters.
